Specifications
Its has a large backlit LCD panel display.
It has the provision to use a hot wire anemometer probe for measurement of air velocity with a resolution of 0.01 m/s in the range 0 to +20 m/s.
A vane anemometer probe is also used for velocity measurement from 0 to +60 m/s.
The vane anemometer does measurements with a resolution of 0.1 m/s (16 mm vane) and 0.01 m/s (60 + 100 mm vane).
It can measure ambient CO2 concentration from 0 to 10000 ppm with a resolution of 1 ppm CO2 using the IAQ probe.
The lux sensor probe has a resolution of 1 Lux which can measure light intensities from 0 to +100000 lux.
It can measure differential pressure using an internal piezoresistive sensor to measure differential pressure with a measuring range of 0 to +25 hPa and overload value of 200 hPa.
The piezoresistive sensor can do measurements with a resolution of 0.01 hPa and accuracy of ± 0.02 hPa (0 to +2 hPa) and ± 1 % of mv (remaining range).
The instrument is powered by 3 AA batteries.
It can last for about 200 hours for typical vane measurements.
Absolute pressure measurements can be performed from 0 to 2000 hPa with an accuracy of ± 5 hPa and a resolution of 0.1 hPa.
It is IP54 certified.
It has provision to use NTC, TC Type T (Cu-CuNi) and TC Type K(NiCr-Ni) probes for temperature measurements.
The NTC probe has a resolution of 0.1 °C is for the temperature range of -50 to +150 °C.
The TC Type K has a measurement range of -200 to +1370 °C with an accuracy of ± (0.3 °C + 0.1 % of mv) and ± (0.2 °C + 0.5 % of mv) (remaining range) and a resolution of 0.1 °C.
The TC Type T probe is used for temperature between -200 °C and +400 °C with a resolution of 0.1 °C and accuracy of ± (0.3 °C + 0.1 % of mv) and ± (0.2 °C + 0.5 % of mv) (remaining range).
A capacitive humidity sensor with a resolution of 0.1 %RH is used for humidity measurements.
It can measure humidity over the entire range of 0 to 100 %RH.
The instrument weighs 428 g.
It is of dimensions 220 X 74 X 46 mm.
It has a housing made of ABS, TPE and metal which is suitable for rugged use.
It is advised to operate the device between -20 °C and +40 °C for proper measurements.
It is advised to store the device under temperatures between -30 °C and +70 °C.
It can store up to 10000 measured values in its memory.
