Detection Instrumentation & Monitors

Detection Instrumentation & Monitors

Detection products from 3M are rugged, reliable instrumentation and software systems that detect, monitor, measure, evaluate and report occupational and environmental health and safety hazards.

Particulate and Air Monitors

Particulate and Indoor Air Quality

Particulate and Indoor Air Quality

The EVM Series of 3M™ Monitors, monitor both particulates and air quality in one compact instrument. This durable, easy to use model provides simultaneous worksite area monitoring of:

  • Particulate mass concentrations (0.1-10 um)
  • Select volatile organic compounds
  • Temperature
  • Relative humidity
  • Carbon dioxide
  • Select toxic gases
  • Air velocity (with purchase of optional accessory)

Heat Stress Monitors

Heat Stress Monitors

Heat Stress Monitors

Heat stress prevention begins with the accurate measurement and analysis of heat stress in the workplace. The series of 3M™ QUESTemp° Heat Stress Monitors provide safety professionals with the durable, easy-to-use instrumentation needed to measure and analyze heat stress related exposure levels.

From manufacturing to military applications, there is a QUESTemp° heat stress monitor for your application.

Waterless Web Bulb
QUESTemp° heat stress monitors 44/46/48N utilize a waterless wet bulb sensor. A humidity sensor and an algorithm perform the calculation of WBGT values, eliminating the need for daily wet bulb maintenance.

Optional Air Probe
The QT36 Series of QUESTemp° heat stress monitors are designed to quickly and accurately evaluate potential heat stress environments. Optional air probe accessory for calculation of PMV/PPD thermal comfort indices.

Personal Monitoring
These personal monitors are compact in size with belt or pocket attachment for convenience. 3M™ E-A-R™ Earlink, covers ear canal sensor for comfortable warning if deep body core temperatures are reached. They also have minute-by-minute data logging and are intrinsic safety certified.
