PCE-WM1 is a multi-function environmental meter used to determine relative humidity (% RH), absolute humidity (g/m³), air temperature, dew-point temperature and surface temperature (°C). This Metric-only measuring instrument comes complete with an external sensor probe for taking the surface temperature of different materials.
- Temperature range: -20 ... 80°C
- Relative humidity range: 10 ... 95% RH
- Absolute humidity range: 0.5 ... 74.4 g/m³
The environmental meter is a class 2 data logging sound level meter that meets IEC 60651:1979, IEC 60804:2000, IEC 61672-1:2013, ANSI S1.4-1983 and ANSI S1.43-1997 requirements. This portable high-accuracy environmental meter has a large easy-to-read illuminated LCD screen that displays the sound pressure level (SPL) numerically and graphically in real time. The sound level data logger calculates the equivalent continuous sound level Leq (LXeq).
- Measuring range: 25 ... 136 db(A)
- LXY (SPL), Leq (LXeq), LXYSD, LXSEL, LXE, LXYmax, LXYmin, LXPeak, LXN
- Frequency weighting: A, B, C and Z
