The Acrulog™ IPX H2S Dilution Monitor has been designed to continually measure and record high PPM levels (0-20ppm, 0-200ppm, or 0-2000ppm) of H2S in indoor and outdoor environments. Featuring remote-draw sampling capabilities from up to 5 meters away, the H2S monitor uses a built in sample pump and dilution system designed for precision mixing of filtered air to reduce sensor exposure and moisture to ensure accurate readings.

The Acrulog H2S Dilution Monitor also has a 4-20mA industrial output and has multiple power options, with exchangeable internal batteries, as well as being compatible with an external power input via the waterproof cable provided (5V).
All logged data can then be easily logged and downloaded via Bluetooth and viewed in the custom graphing and data analysis Acrustat software. 

The Acrulog™ IPX H2S Dilution Monitor is rugged, accurate and provides a cost-effective solution for monitoring PPM levels of H2S.
