New, easy to use environmental monitor combines several instruments into one.

• Simultaneously measures and logs particulates (mass concentration), volatile organic compounds (VOCs), toxic gas, carbon dioxide (CO2), relative humidity, temperature and air velocity (with optional accessory).
• Provides a cost-effective solution and reduces the need for multiple instruments.

Real-Time Direct Reading Particulate Monitor

• Features patent-pending dial-in impactor system for quick particulate selection.
• Built-in sampling pump assists in the collection of particulates while the light scattering photometer mass concentration engine provides real-time measurement.
• Insert a standard 37 mm cassette for gravimetric sampling and laboratory analysis. Comprehensive PID and Smart Sensor Measurement
• High-performance Photoionization Detector (PID) measures volatile organic compounds(VOCs).

• Smart sensors offer automatic recognition at power-on and store sensor specific information.
• Download data into QuestSuite®Professional II for detailed analysis.

EVM-3 Environmental Monitor

Real-Time Direct Reading Particulate Monitor.

The EVM-3 provides real-time direct reading of particulate concentrations, along with temperature and relative humidity measurements. The patent-pending dial-in impactors allow for quick selection of particulate settings PM2.5, PM4, PM10 or TSP (within the instrument's measurement range) without disassembly.

A built-in air sampling pump assists in the collection of particulates while the laser photometer provides real-time measurement. A standard 25 or 37 mm gravimetric cassette can be utilized for sampling and laboratory analysis, and help provide correlation for real-time direct reading measurements.

EVM-4 Environmental Monitor

Comprehensive Indoor Air Quality Analysis.

The EVM-4 is designed for comprehensive indoor air quality analysis with its ability to simultaneously monitor and log one toxic gas, carbon dioxide, relative humidity and temperature.

The instrument's compact size and displayed overview of parameters make indoor air quality assessment easy.

This versatile monitor features a tripod mount and security code protection for unattended stationary studies.

Additionally, the EVM-4 offers calculation of room air exchange rates with carbon dioxide trending algorithms for in-depth air quality evaluation (with QuestSuite? Professional II software).

The datalogging QUESTemp° 36 is the premier monitor within the QUESTemp° Series of Thermal Environment Monitors.

The QUESTemp° 36 further simplifies heat stress management efforts by providing users with realtime guidance on stay times and work/rest regimens. Guidance is based on screening criteria for heat stress as defined in the ACGIH TLV Handbook,U.S. Navy PHEL Charts and EPRI Action Limits.

The QUESTemp° 36 eliminates the need to carry paper charts, pocket guides and look-up tables into the field.

An optional detachable probe for measuring air velocity extends the applications for the QUESTemp° 36 beyond traditional heat stress measurements. The QUESTemp° 36 can be used as an indoor thermal comfort monitor using the air velocity probe, temperature and RH sensor readings simultaneously.

Other applications include verification of air flow in fume hoods or rooms normally requiring a minimum amount of air flow to be safe for occupancy.

The QUESTemp° II is a datalogging Personal Heat Stress Monitor. Based on extensive research funded by the Electric Power Research institute and performed by Westinghouse Electric and Pennsylvania State University, it monitors both body temperature and heart rate to calculate individual body strain in response to heat stress.

It uses a two-stage audio/visual alarm. The first stage "Warning Alert" indicates that conditions are approaching a level where there is a limited amount of time to work. The second stage "Action Alert" indicates that the worker should stop work immediately and take necessary actions.

The watertight lightweight monitor assembly can be slipped into a shirt pocket or clipped to a belt while the elastic sensor belt assembly is worn comfortably around the chest. It is programmable for the appropriate age group and clothing type of the individual being monitored.

Heart rate, temperature, and heat strain alert status are recorded once every minute and stamped with the date and time to correlate events and pinpoint problems.

Output recorded data directly to a serial printer or download to QuestSuite Professional software, "The System Solution" for storage, retrieval, analysis, reporting, and charting of all your heat stress monitoring data.
