Mercury Analyzer

Monitor for work place air: EMP-1A

To ensure the environmental and health safety of all workers in the ambient work area, the current Occupational Safety and Health Administration (OSHA) permissible exposure limit (PEL) for mercury vapor is 0.1 milligram per cubic meter (mg/m3) of air as a ceiling limit. Therefore, a worker exposure to mercury vapor should not exceed this ceiling level.

Similarly, the National Institute for Occupational Safety and Health (NIOSH) has also established a recommended exposure limit (REL) for mercury vapor of 0.05mg/m3 as a time-weighed average (TWA) for up to a 10-hour workday and a 40-hour workweek. This level The NIOSH limit is based on the risk of central nervous system damage, eye, skin, and respiratory tract irritation.

Both models of Mercury Monitors below are applicable for determining the mercury vapor level in ambient air.

Model EMP-1A Mercury Handheld Meter is built to provide all operators a handy, quick and easily way to obtain an instant real-time measurement of mercury with great precision. A reliable membrane pump draws the air sample through its handheld probe, exposing the air stream under UV 253.7nm generated from a low-pressure long-life mercury discharge lamp. The absorbed mercury amount is continuously quantified and display on the LCD screen. EMP-1A has sensitivity down to 0.001mg/m3.

The unit is equipped with re-chargeable Ni-MH battery, which enables continuous 10-hours long operation in the field or site. Moreover, it is designed with data-logging function to allow mercury readings recording up to 100 data. High-Alarm setting feature allows setting of user safety threshold level for mercury detection in ambient air at their convenience.

Each package of EMP-1A comes complete with EMP-1A Mercury Meter, a Sampling Probe and Charger, all in a compact carrying case.

Mercury Gas monitor The model EMP-1A is easily-portable battery-powered mercury measuring equipment. This model passes sample gas directly into the quartz cell of the cold-vapor atomic-absorption mercury analyzer, thus allowing measurement result confirmation in real time. And besides that, this model has an alarm for when the concentration of mercury exceeds a preset value.
