The Testo 400
Testo New Professional Class - The reference measuring
instruments
testo 400 is the multi-function instrument designed to simplify the measuring tasks of professionals and tradesmen.
The testo 400 measures and records:
- Temperature with accuracies to <0.1 °C/°F. Probes have calibration for adjustment capabilities.
- Humidity/Dew point, complete Mollier diagram values.
- CO and CO2 with ambient levels
- pressure, differential pressure and also absolute pressure
- Velocity measurements using thermal, vane and pitot tube probes.
- It also calculates volumne flow, max, min and values mention of ASHRAE Speck's
- The mV/mA measurement input easily checks transducers outputs.
- Logs data with date, time and location over long time periods using the logger function in the measuring instrument.
Equipped for the future
The
following functions are upgradable (available in mid
1998):
- The measuring instrument guides you through volume flow calculations and calculates, for example, immerson depths, number of measuring points etc.
- Calculates measuring inaccuracies on location
Description
The precision multifunction instrument and datalogger measures temperature, CO, CO2, rpm, mV and mA, % RH, pressure and velocity.
- Rapid measurement with accurate temperature probes.
The instrument can extrapolate the final value for faster response times. - Highest precision due to system calibration (measuring instrument +
probe)
Calibration data is saved in the probe. - Calculates all of the physical humidity parameters in the Mollier
diagram:
- relativ humidity (% RH)
- dew point, pressure dew point (tp, tdp)
- absolute humidity (g/m3)
- humidity levels (g/kg pressure-compensated)
- humidity, wet temperature °C and °F
- water vapour partial pressure in mbar/hPa
- Enthalpy kcal/kg - Humidity probes for every application, from remaining humidity to high humidity levels
- Indent guaranteed long-term stability
- Highest accuarcy ± 1 %
- All of the conventional types of averaging are available
- Volume flow measurement (cfm, m3/min, l/s)
- Duct dimensions in the various measurement locations can be saved in the instrument. When the measurement location is called up the saved dimensions can be used to measure cfm.
- Measures the barometric pressure (absolute pressure) as a reference value or for the correct Pitot tube measurement.
- Measures turbulence levels.
Features:
- Measuring instrument and display are integrated in the probe
- Very practical one-hand operation
- No awkward cable connections
- Robust, waterproof design, can be wiped clean
