Micro IV Pump

Before and after entering a shaft, duct or tank, the pump can be used to continuously monitor the entry area. Dangers from toxic or flammable gases as well as from oxygen deficiency can thus be controlled from a safe distance.

Easy handling
The pump is simply attached to the Micro IV. This allows the handy gas detection device to be used for remote monitoring to clear confined spaces before and during entry. The high-performance pump draws in gas samples without exposing anyone to the potentially dangerous atmosphere. If the flow rate falls below the minimum or the battery is low, a visual alarm is triggered.

Equipment and accessories
The flow rate of the attachable pump for the Micro IV is up to 0.5 l/m. Two batteries (type AA) provide their own power supply independent of the gas detection device. A green LED indicates the operating status. With an operating time of up to eight hours in continuous operation, permanent clearance is possible even during longer jobs. Like the Micro IV, the pump is approved for Ex Zone 1. Accessories include a telescopic suction tube, special test hoses and a floating probe.

DS220

The DS220 docking station enables fully automatic and simultaneous testing of six Micro IVs, which means significant time savings and faster operational readiness of the gas detectors. The bump test starts automatically after the slots are loaded and includes tests of response time, alarm thresholds, visual and audible alarms, and more. The test process and the test result are indicated with LEDs in green, yellow or red for each Micro IV. Only gas detection devices that are checked every working day contribute reliably to safety.

Adjustment
In addition to the daily function test required by DGUV information 213-056 (T021) and 213-057 (T023), the DS220 can also be used to adjust the sensor on the Micro IV. The docking station indicates whether a gas detector needs to be adjusted and automatically sets the adjustment interval. The gas for the adjustment of the sensors is sucked in via the integrated pump (0.5 l/m) of the docking station. This allows up to six Micro IVs to be adjusted in parallel with the same gas and gas concentration.

Operation and documentation
Operation is carried out via two keys on the top of the docking station. The green key turns the DS220 on and off, the red key switches between test and calibration mode. The docking station stores the data on an SD memory card. The information from the function tests and adjustments can be transferred to the PC either via a card reader or direct connection. The docking station can also be parameterized via configuration software.

Equipment and accessories
Power is supplied via an external 12 V power supply unit. Connection to a computer for reading out and saving the device-related data stored in the docking station is via RS-485 (using a USB adapter). With optional patch cables, several docking stations can also be connected via this interface. Two gas inputs for zero and test gas as well as six gas outputs are located on the rear panel. Various gas sampling fittings and pressure switches are offered for the test gas task.

DI220

The space-saving DI220 data interface accommodates a Micro IV gas detector. The meter’s data memory is read out via the infrared interface and records up to 200 events such as alarm limit values as well as short- and long-term values including gas concentration and time.

Equipment and accessories
Connection to a computer is via the USB interface, as is the power supply. The software for reading out and configuring the unit on a PC is supplied on CD.

G888/999 Visual

G888/G999 Visual can be used instead of or in combination with a TeamLink. The status and measured values of each individual gas detection device are displayed in a clearly structured overview on a PC screen, laptop or tablet PC. In the event of an alarm, the colored background changes from green to red for the team member concerned. An interrupted connection is signaled in yellow. Short messages can be sent to the gas detection devices from the computer. These can be answered easily via the pager function (e.g. “Are you okay?” > “Yes”).

The G888/G999 Visual software can be installed on PCs and laptops with the Windows operating system and on tablets. A USB dongle is required for the radio connection to the portable gas detection devices with radio module (optional). The range of the radio connection is up to 700 m. Radio communication takes place in the 868 MHz band (Europe and Africa) or in the 915 MHz band (North and South America).

G400-MP2

The G400-MP2 is attached to a G450 or G460. When the pump is switched on, the diffusion openings of the gas detection device are covered so that the measurement results are not influenced by the ambient air. Faults in the pump are also indicated on the gas detector’s display thanks to smart communication with the gas detector. The pump’s own power supply ensures that the gas detection device’s battery life is not shortened during pump operation.

Equipment and technique
Thanks to the high under-pressure performance, confined spaces such as ducts, cellars and tanks can be cleared from a safe distance before and while they are entered by people with portable gas detection devices. The flow rate is up to 0.5 liters per minute. With an alkaline battery, 10 hours of continuous operation of the pump is possible, with NiMH battery even 12 hours. Like the G450 and G460 gas detection devices, both the battery and the rechargeable battery are approved for Ex zone 1.

DIC 888/999

Charging cradle for stationary or mobile operation
Portable gas detection devices and safety monitors must be ready to operate when needed. A full battery ensures the maximum operating time to be able to warn of dangerous gases or oxygen deficiency during the entire operation. To make charging the G999 and G888 gas detection devices and TeamLink quick and easy, we have developed the DIC888/999-B charging cradle. Power is supplied via an optional power supply unit or a car charging adapter.

TS/TX 400

Before each use of a portable gas detection device, its flawless functionality must be checked with a display test (bump test). We have developed the TS400 and TX400 test stations for our G450 and G460 portable devices so that this measure, which is required by DGUV information 213-056 (T021) and 213-057 (T023), is simple, time-saving and cost-effective. During the functional test, operation is via the display and the keys of the inserted measuring device.

Function test and adjustment
If a switched-on gas detection device is inserted into one of the two test stations, the function test starts automatically after ten seconds. Within a maximum of 30 seconds, the alarms and response times are tested, the time and test interval are set, and the data is stored on a microSD card (optional). Afterwards, it is displayed whether the test has been performed successfully or whether an error has occurred. The TX400 also offers the option of sensor adjustment. Before adjustment, the zero point of the sensors must be set with fresh air. The sensor sensitivity is then readjusted using the appropriate test gas. Depending on the device and the number of sensors, this process takes a maximum of four minutes.

Power supply and charging function (optional)
Power is supplied via an external 12-volt power supply unit or via a PC connected by USB. If a switched-off gas detection device is placed in the test station, the charging process starts automatically. Once fully charged, the test station switches to trickle charge to conserve battery power. A 230 volt power supply or a car charging adapter is required for the charging function.
