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.
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.
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/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).
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.
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.
