TRH320 | -40°C to 70°C | ±0.3°C | ±2.0 %RH | Pet mesh | PVC | Yes |
TRH200 | -40°C to 70°C | ±0.3°C | ±2.0 %RH | None | PVC | No |
Note: The above is a summary meant to highlight key differences. Please refer to individual product pages and datasheet for complete specifications.
Particle filter
Some models include a thin PTFE membrane designed to block more than 99.99% of particles in excess of 200nm. This is recommended for harsh environments where extra protection against dust, soot and other contaminents is a requirement.
Enclosure types
The enclosure is what covers the digital sensor probe.
Cable type
Most models use standard PVC cables, but high temperature range models use Silicon cables.
- PVC: Low cost standard cable type, medium temperature range. Not suitable for extreme temperatures. Can crack if flexed at low temperature.
- Silicon: High temperature resistance, stays flexible even at low temperatures.
