Feb 2000 Analytical Instrumentation & Environmental Monitoring

The Oldham MX21 Plus multigas detector is a portable multigas monitor which can detect up to four gases simultaneously and is capable of monitoring a range of explosive and toxic gases plus oxygen according to application requirements. The MX21 Plus also has the ability to measure air velocity temperature etc by the use of intelligent plug-in modules.

The MX21 has one of the largest available range of toxic sensors, plus oxygen (O2) and flammable gases (0-100% LEL and 0-100% v/v). Standard toxic gas modules include CO, CO2, H2S, SO2, CL2, NO, NO2, HCL, HCN, NH3, H2, PH3, O3, VCM, ASH3, HF, solvents, etc.

The intelligent sensor modules allow the user to have one instrument that can be configured for varying applications.

All data is retained in the MX21 Plus for download of diagnostics to PC including wear rate, calibration data, exposure graphs, manufacture data, etc. A full range of accessories is available including cases, sampling equipment with pump, 220 V and 12 V d.c. charger etc.

The unique format of the MX21 Plus allows use in a wide variation of applications including occupational hygiene surveys, mine ventilation, personal safety, leak detection, etc. Main features include cross sensitivity compensation, flammable gas automatic programming and long life sensors.

The unit is SABS1515 approved and EEx ia d11CT4.
