Frequently Asked Questions

What is the Dwyer AVG-2A121 thermistor probe used for?

The Dwyer AVG-2A121 thermistor probe measures average air temperature upstream of cooling coils in HVAC and process control systems. Its flexible copper capillary and bracket-mount design enable reliable remote sensing across a large area, making it suitable for building management and industrial temperature monitoring.

What are the specifications of the Dwyer AVG-2A121 probe?

The Dwyer AVG-2A121 features a 2252K OHM thermistor sensor with ±0.36°F accuracy from 0 to +70°C. It has a 30 cm flexible copper capillary, 20 cm cable, bracket clamps for mounting, and an operating temperature range of -35.5 to +115.5°C. The housing includes conduit knockouts for installation.

Where to buy the Dwyer AVG-2A121 in Singapore?

3G Electric supplies the Dwyer AVG-2A121 thermistor probe to Singapore. We handle sourcing, logistics, customs clearance, and delivery to your facility. Contact our team for pricing and lead time on this model. We provide technical support for HVAC and process control applications locally.

How to install the Dwyer AVG-2A121 average temperature probe?

Mount the Dwyer AVG-2A121 using the bracket clamps to secure the probe to the air duct wall. Uncoil the flexible copper capillary across the cooling coil face for an average temperature reading. Use the conduit knockouts for wiring access. Ensure the capillary lies flat without kinking for accurate sensing.
