Verifying the temperature indication
To ensure that the results of the adjustment operations
described below are reliable, the following minimum
immersion depths should be maintained:
•
60 mm for bimetallic thermometers-types TS, TH, TM, TK
•
70, 120, 220 mm (ls+20) – according to bulb type –
for gas pressure thermometers (types TF, TG).
These lengths are indicated by a welding seam around
the bulb.
The reference temperature
If the temperature of the medium (liquid, gas) in which the
stem or the bulb is immersed is not known, and neither a
correctly calibrated reference thermometer is placed nearby, or
a calibration bath (filled with oil or water and stirred)
is available, the instrument can be verified by either of the
following two simple methods:
a. Immerse the thermometer stem or the bulb in melting ice
(ratio ice: water approx. 2:1) and stir it around. After about
5 minutes – the time to allow the measuring system to
stabilize – the thermometer should indicate 0°C.
b. Immerse the thermometer stem or the bulb in boiling
water. After about 5 minutes – the time to allow the
measuring system to stabilize – the thermometer should
indicate:
100 °C at 0 m (sea level)
99 °C at 327 m
98 °C at 654 m
The temperature of boiling water at other altitudes can be
found by assuming a drop of 1°C per 327 m height increase.
In this approximate but often useful method, temporary
atmospheric pressure variations can be neglected.
Important ! Verification and adjustment at ambient
temperature are not recommended.
Verifying, setting and readjusting Rüeger Thermometers
All these thermometers, designed to meet the most demanding requirements, are provided with one or several adjust-
ment devices. These devices allow :
• setting to a given working temperature, for accurate indication and the compensation of errors due to the
measuring point
• readjustment, for example after long use under severe vibrations or frequent shocks
• rotation of the dial (type TMH).
• resetting after rotating the dial (types TMV... and TMI...), for example to orient the stem in a different direction
• alignment of a thermometer mounted in a row
• setting switchpoints of electrical switching thermometers from the outside; types TM (H, V, I) K, TG (H, V, I) K,
TF (H, V) K
• external resetting of thermometers with pierced case; types TH (H, I)

Summary

Verifying, Setting, and Readjusting Rüeger Thermometers

Verifying Temperature Indication

Ensure adjustment reliability by maintaining minimum immersion depths for thermometers.

The Reference Temperature

Verify instruments by immersing in melting ice or boiling water for accurate temperature readings.

Adjustment by Dial Rotation

External Adjustment (Pierced Glass)

Adjust dial graduation for TMH group via external device with pierced glass.

External Adjustment (±10°)

Adjust dial for TH (H, I) thermometers using an external device and screwdriver.

Adjustment by Pointer Repositioning

Adjustment for Thermo-STANDARD Group

Reposition pointer for STANDARD thermometers using setting tool 225-002.

Adjustment for MODUL, FLEXIBLE, KONTAKT Thermometers

Reposition pointer for MODUL, FLEXIBLE, KONTAKT thermometers using setting tool 225-003.

Adjustment by Dial Rotation with External Device

Dial Rotation with External Device for TMH

Rotate dial of TMH thermometers using an external device fixed to the glass.

Adjusting Switchpoints on Electrical Thermometers

Switchpoint Adjustment for MODUL/FLEXIBLE

Adjust electrical switchpoints for MODUL (TM K) and FLEXIBLE (TF K) thermometers.

Bottom-Connected Bimetallic Thermometers (TMV)

Dial Rotation and Readjustment for TMV

Rotate dial of TMV thermometers as per method A; readjust as per method B.

Tilting and Rotating Thermometer Heads

Tilting the Head (0-90°)

Adjust the thermometer head angle between 0-90 degrees by loosening and retightening screws.

Rotating the Head (360°)

Rotate the thermometer head 360 degrees by loosening and retightening locknuts.

Storage of Thermometers

Storage Conditions

Store thermometers in original packaging, protected from shocks, vibrations, dust, and humidity.
