The environmental tester 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 tester 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 tester 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
• Time weighting: Fast (125 ms), slow (1 sec) and impulse (35 ms), decay (1500 ms)
• adjustable data-recording interval from 1 s … 24 h
• 1/1 octave band filter (optional 1/3 octave band filter upgrade)

• Measuring range up to 20,000 A/cm
• Angled axial probe
• AC, DC and pulse measurements
• Measurement of residual magnetism possible

An electrostatic measurement is particularly important to check whether surfaces, components or the human body are electrostatically charged. Such electrostatic charges can be detected with the environmental tester.

• Measuring range: ±60 kV DC
• Acoustic signal when the measured value is exceeded
• Temperature and humidity display
• Laser for aligning the measuring device

The environmental tester is used in offices, workshops or in laboratories to carry out indicative measurements of the environmental conditions. In addition to the number of particles, the environmental tester determines the mass concentration of PM2.5 and PM10 in the measuring range 0 … 1000 µg/m³.

• Measurable particle sizes: PM2.5 / PM10
• Particle sizes: 0.3 / 0.5 / 1.0 / 2.5 / 5.0 and 10 µm
• Mass concentration
• Particle counter
• Temperature
• Humidity (RH)
• Flash memory for approx. 12 measurement runs

The environmental tester is a measuring device for stationary measurement of relative humidity and temperature. This environmental tester consists of an LED seven-segment display with a digit height of 100 mm, which enables you to read it very well even at a distance of up to 50 m.

• Temperature measuring range: 0 … +60 °C (Celsius only)
• Humidity measuring range: 10 … 95 % RH
• Up to 50 m (164 ft) reading distance
• External sensor (wired)
• Voltage supply: 230 V AC
• with analogue output 4 … 20 mA

The environmental tester is intended for stationary measurement of relative humidity and temperature and direct display on a large display. This environmental tester consists of an LED display (100 mm high) and is protected according to IP 54.

• Temperature measuring range: 0 … +60 °C (Celsius only)
• Humidity measuring range: 10 … 95 % RH
• Up to 50 m (164 ft) reading distance
• External sensor (wired)
