Features

Digital thermometer DT-511 is used to measure the temperature of different medium, relative humidity of the air by direct contact of the probe with measurement object.

The device has two measuring channels for connecting two probes at the same time and displaying information from both of them.

Thermometer consists of electronic unit and replaceable probes.

As thermosensitive elements in probes thermocouples are used.

As measuring element in relative humidity probes capacitive humidity sensors are used.

Simultaneous measurement of humidity and temperature in any combination through two channels with one device.
Measuring the temperature with resolution 0,1°С.
Measuring the relative humidity with resolution 0,1%.
Changeable probe.
Working simultaneously with two probes.
9 memory cells for storing measurement readings.
Measuring the atmospheric pressure.
Displaying the temperature of the thermal compensation sensor on the screen.
Displaying the air temperature when using the humidity probe.
Fixating measured temperature and humidity in the device's memory.
Displaying the average temperature and humidity for a given number of measurements.
Displaying the maximum temperature and humidity (for a given number of measurements).
Displaying the minimum temperature and humidity (for a given number of measurements).
Setting measured temperature and humidity limits.
Sound indication after reaching the set level of measured temperature and humidity.
Automatic saving when switching off the current, averaged, max, min supply voltage, remaining operating time of the device.
1 year manufacturer's warranty.
Powered by standard AA batteries.

Purpose

DT-511 is used for highly precise measurement of temperature, humidity and dew point temperature by direct contact with the measurement object.

Due to the possibility of changing the probe, measurements can be carried out for almost any media: liquid, dry, solid.

Improved devices allow using high-precision probes for:

high-precision surface measurements;
high-precision air temperature measurements;
work with thermocouples of types K, L, B, R, S;
high-precision atmospheric pressure measurements;
simultaneous high-precision measurement of temperature and humidity.

Calibration

All DT-5 digital thermometers are calibrated and certified as measurement instruments in Russia, Kazakhstan, Belarus.
