Acrulog H2S Parts Per Billion Monitor

The Acrulog™ H2S Parts Per Billion Monitor (PPB) is a portable gas data-logger designed for indoor and outdoor environmental applications, to record low levels (0-2000PPB) of Hydrogen Sulphide (H2S), at sampling intervals of between 10 minutes and 1 hour.

Standard model features built-in sample pump, internal batteries. Optional outputs: 4-20mA, RS485, 4G LTE-M or NB-IoT. External power input is available and included with the 4-20mA or RS485 cable waterproof cable (5-15VDC).

The Acrulog™ H2S Parts Per Billion Monitor (PPB) logs and provides data to ensure that offensive and nuisance odour emissions are within acceptable environmental levels.

All logged data can then be easily logged and downloaded via Bluetooth® wireless technology and viewed in the custom graphing and data analysis Acrustat software.
