Tested Working Air Techniques Hamilton Aerosol Photometer 2H-N 2H Nuclear Optical Particle Detector OPD
Tested: works and interacts with the tests performed by our technician, see video: youtube.com/watch?v=irh5lsp_hvg
Tested within standard range for ambient air quality and detected air particles such as dust which proves the operation of this instrument. Not calibrated. Scanning probe not included in purchase.
From the manufacturer: "The 2H is a forward light-scattering, linear photometer. It operates on 100 to 240 Volts, 50 or 60 Hz, adjusting automatically. The basic function of the 2H is to sample air or other gases and report the mass concentration of particulates in the sample. This unit is also available in a nuclear version, the 2H-N. The nuclear version is the same size and has the same features as the 2H, plus a sealed sampling chamber and an additional ULPA filter to contain all contamination within the unit.
The 2H is compact and lightweight. The instrument case is constructed of die cast aluminum and has a swing arm carrying handle that folds up under the case to tilt the unit for easy viewing. The pressure-sensitive keypad and large, bright LED displays and indicators provide ease of operation and readability. The auto-ranging and one-step zeroing features assure the accuracy of all readings."
