To meet cleanroom standards, environmental sensors are used to monitor the environment. The data from the sensors are either recorded manually or logged electronically through a monitoring system.


Depending on the application, different types of sensors are used. The most popular sensors are temperature, relative humidity, and differential pressure. However, Acumen can offer a wide variety of sensors (see right).

  • Temperature

  • Relative Humidity

  • Differential Pressure

  • Air Velocity

  • Particle Counts (Non-Viable)

  • Particle Counts (Viable)

  • Door Status

  • Carbon Monoxide Levels

  • Oxygen Levels






Remote TRH Sensor

The Remote TRH sensor is a cost effective and highly accurate sensor designed for cleanroom and controlled environment applications. 

The Remote TRH sensor is available in two models TRH-03-25 and TRH-02-15. The TRH-03-25 comes with ±0.3°C and ±2.5% RH accuracy. The TRH-02-15 is available with a display option and ±0.2°C and ±1.5% RH accuracy. The Remote sensor uses the latest sensor technology which offers long-term stability and resistance against pollutants. With NIST Traceable multipoint calibration and IP65/NEMA 4 rated enclosure, the Remote TRH is ideal for cleanroom applications.

Temperature Sensor

The Remote RTD is a small cost effective high accuracy temperature sensor suited for cleanroom applications and for monitoring of laboratory equipment where product is stored. This sensor is ideal for incubator, oven, fridge and freezer applications in your facility or basic room monitoring.

With NIST traceable multipoint calibration and IP65 rating this is the perfect instrument for all critical monitoring applications.


Differential Pressure

The Remote DP Sensor combines a flexible field selectable range, output and calibration options. A local display allows for cleanroom personnel to easily identify room pressure conditions.

The Remote DP Sensor has an accuracy of +/- 1% or can come with a more sensitive 0.5% accuracy over the full range. With NIST Traceable multipoint calibration and IP67 rating, this is the perfect instrument for all critical monitoring applications.


Air Velocity

The Remote AV Sensor is the ideal solution for unidirectional flow and ventilation monitoring in cleanroom environments and for HVAC applications.

The Remote AV Sensor has a highly accurate sensor for measurement of low air velocity and is most suitable for cleanroom and controlled environment device monitoring such as isolators, cabinets and biological safety cabinets. 

With NIST Traceable multipoint calibration, optional local display and IP65 rating this is the perfect instrument for all critical monitoring applications.
