Q: How does the A43 thermometer measure temperature?
A: It uses a bimetallic coil that expands and contracts with temperature changes, moving the pointer to indicate the measured temperature.
Q: Does the A43 require electricity to operate?
A: No ā the thermometer works mechanically and does not require any external power supply.
Q: Where is the A43 commonly used?
A: It is commonly installed in HVAC systems, machinery, pipelines and tanks for local temperature indication.
Q: Can it be mounted directly into pipes or tanks?
A: Yes ā with the correct threaded process connection and stem length, it can be installed directly into pipelines or vessels.
