Multigas detector Industrial Scientific Ventis MX4

Multi-gas detector Industrial Scientific Ventis MX4 is a robust gas detector that can be equipped with a pump and sensors for up to four different gases.
It has a large illuminated LCD display which, among other things, shows measured values ​​and gas type. Alarm indication occurs with a powerful (95 dB) siren, intense flashing light and vibration. Ventis also alarms when the hygienic limit values ​​for toxic gases are exceeded.
The instrument is compatible with iNet™ (monitoring of the instrument's status via the Internet) and DS2™ docking station for automatic calibration and V-Cal docking station for functional testing, calibration and transfer of logged data to computer.
Ventis without pump is supplied with charger for 230 volts, belt clip, calibration hood and hose for manual calibration.
Ventis with pump is supplied with charger for 230 volts, approximately 3 meters of sampling hose and hose for manual calibration.
