Flexible mounting system for temperature and humidity sensorsThe mapping system features eleven sensor mounts made from flexible and insulating silicone. This isolates the temperature sensors from the stainless-steel mounting rods, also incorporating an intelligent cable routing system. You can use temperature probes with a diameter of 3 to 6 mm in a temperature range of -50 °C to +200 °C. The mounting rods are constructed so that the user can position the temperature sensors in the top and bottom corners (8), as well as the vertical center line of the chamber, giving you a 360° temperature or humidity profile.
Uniformity of humidityIn combination with a dew point chilled mirror hygrometer, temperature uniformity data can be combined with dew point data for relative humidity uniformity studies.
Multi-channel Temperature Measurement System
Model T12 is a multi-channel temperature measurement system that provides high-precision temperature data from up to 12 sensors for calibration and validation purposes. It is ideal for climate chamber validation applications where temperature uniformity is a significant contributor to overall system uncertainty. Using multiple probes connected to the T12 allow a spatial temperature measurement so you can visualize gradients within the chamber.
The high precision and long term stability of the T12 and its connected Pt-100 probes enable test engineers to precisely establish the temperature and its distribution. Using a chilled mirror device, T12 temperature data can be combined with dew point or frost point data to define the relative humidity distribution within a test or stability chamber. This methodology is defined as part of test standards and guidelines such as EC60068-1, DKD-R 5-7, Euramet-cg-20 and NF X 15-140.
Features of the multi-channel thermometer
- High precision, stability and repeatability
- Integrated high-stability reference resistors
- 22-bit analog-to-digital converter
- PC software for instrument control and data acquisition
- Dedicated versions for Pt-100 and Pt-25
The dew-point mirror model 473 is a portable instrument equipped with a remote measuring head for selective and continuous measurement of dew point and temperature in air and gas mixtures. Based on the chilled mirror principle, the 473 provides direct and accurate humidity measurements.
The frost/dew point measurement can be combined with a multi-channel temperature measurement device such as the MBW T12. Such a system offers spatial temperature and RH distribution measurements, which can be displayed, recorded and analyzed for validation purposes.

Climate Chamber ValidationThe validation of a climate chamber should be performed regularly to achieve the required specifications and to comply with laboratory or regulatory standards. Climate chambers can be tested with and without a load depending on the type of product being tested.
During the validation procedure, the chamber is subjected to a functional test with calibrated instruments for humidity and temperature, to establish actual values achieved, the stability of the control mechanism and the spatial distribution or gradients. The choice of instrument used to measure chamber performance affects the uncertainty associated with the chamber calibration.
