HD21 Series Barometer-Manometer-Thermometer
Brand: Delta OHM S.R.L.
Series of portable instruments with LCD display. They measure absolute, relative and differential pressure, as well as temperature.
Pressure is measured using an internal module which is differential with respect to the atmosphere with fixed full scale.
With the PP471 module acting as an interface, the instrument can use all the TP704 and TP705 series Delta OHM probes to perform the measurements.
The HD2114B.0 and HD2114B.2 internal module measures the barometric pressure.
The temperature is detected using immersion, penetration, contact or air probes, with SICRAM module or direct 4-wire probes.
The sensor can be a Pt100 or Pt1000. Temperature probes are equipped with SICRAM module and factory calibration data are stored inside so that when the instrument is on it soon recognizes them.
The HD2114.2, HD2134.2, HD2164.2 and HD2114B.2 instruments are dataloggers.
They store up to 36,000 samples which can be transferred into a PC connected to the serial ports RS232C and USB 2.0 or into a portable printer.
The storing interval, printing, and baud rate can be configured using the menu.
The Max, Min and Avg function calculates the maximum, minimum or average values.
The Peak function can be activated with external probes connected to the module PP471 and detects the presence of pressure peaks.
Other functions include: the relative measurement REL, the HOLD function, and the automatic turning off (excludable).
The instruments have IP66 protection degree.
