1111H, D2, 1211H

The 1111H, D2 and 1211H are chilled mirror sensors for use with Panametrics OptiSonde and Optica analyzers, suited to both new installations and upgrades.

Chilled mirror technology provides a direct measurement of dew and frost point by maintaining a polished mirror at the equilibrium between condensation and evaporation. This primary method delivers stable performance with ±0.2 °C dew point accuracy, with an optional ±0.15 °C dew point specification across all models.

1111H — Single-Stage Sensor
Well suited to laboratory, HVAC and clean gas applications, the 1111H provides 45 °C of mirror depression, giving a typical range down to −15 °C dew point at 25 °C ambient. The upper measurement limit follows the sensor temperature and can extend above typical room conditions when installed in elevated ambient or controlled environments. Rated up to 15 bar (200 psig).

D2 — Two-Stage Sensor
The D2 offers 65 °C of mirror depression, enabling measurement down to −35 °C dew point at 25 °C ambient. As with the 1111H, the maximum dew point increases with operating temperature, allowing measurements above typical room conditions in warmer or controlled environments. Rated up to 11 bar (150 psig).

1211H — High-Pressure, High-Temperature Sensor
The 1211H builds on the D2, combining the same measurement capability with extended pressure (up to 21 bar) and ambient temperature limits (up to 100 °C) for demanding process applications.

All models include the PACER® self-cleaning cycle and can be installed up to 91 m from the analyzer. Platinum mirror options are available.
