Optical Channel

This meter features four optical channels with ST-connectors, compatible to a broad range of fiber-optic and contactless sensors. The optical sensor of your choice must be purchased separately.

Temperature Port

This device is equipped with a LEMO-connector for Pt100 temperature probes, which can be used for automatic temperature compensation of optical sensor measurements, or simply for logging temperatures in liquids and gases.

Integrated Pressure and Humidity Sensors

All FireSting devices come with integrated sensors for atmospheric pressure (mbar) and relative humidity (%RH) of the ambient air for a user-friendly precision calibration procedure in water or ambient air. The integrated pressure sensor can be used for automatic pressure compensation of oxygen measurements performed e.g. in units of %O2, %air saturation or in DO concentration units (µmol/L, mg/L). These oxygen units show a strong dependence on atmospheric pressure changes (weather changes, altitude). Automatic pressure compensation is integrated seamlessly into the included innovative logger software / user interface.

Analog Output

This device has 4 integrated analog outputs (0..2.5V), which can be configured and scaled with the included software. Optionally, each analog output can be also configured as an alarm output (e.g. for control tasks like observing a defined oxygen level in fish tanks).

Broadcast Mode

This meter can be operated optionally without any PC connected in the so-called broadcast mode. Simply activate the broadcast mode by connecting and powering the meter with a standard micro-USB charger (as used for mobile phones). The measured sensor data are read out via the analog output (or via the serial interface of the extension port).
