Temperature Measurement - Testo 252 Bedienungsanleitung

Temperature measurement

Connect the temperature probe. When the
measuring instrument is switched on, the
temperature value appears immediately in the
display (when using an individual, special
temperature probe). Should you use
combination probes, turn to the chapter
"Display variations" to determine the
importance of the different segments of the
display.
As a rule we distinguish between surface,
immersion and penetration measurements as well
as measurements of air/gas temperatures. The
corresponding probe is to be used for each type of
application.
General instructions
for immersion, penetration or air
measurements
- The minimum immersion depth corresponds
with approx. 5 times the diameter of the probe.
- The response times can be accelerated by
gently moving the probe.
for surface measurements
- The tip of the surface probe must be in a
vertical position.
- We recommend the use of heat paste for
measurements on rough surfaces (for a
better heat conductance).
Surface probes are not permissible for
temperature measurements used for
compensation of the pH value (
loops)
