Calibration certificates - Import export

The DKRF470 Series of transducers was designed for sophisticated measurement applications (humidity and temperature) such as in process automation, HVAC in public swimming pools or greenhouses. Based on the latest capacitive sensor technology by Sensirion (CMOSens) the devices provide a precise yet affordable solution for a variety of potential measuring tasks. They are extremely resitant to dust as well as most chemicals and provide high accuracy and reliability (+/-1.8%RH / +/-0.3°C). The sensor head is available as a spare part with or without a certificate of calibration which allows you to change it on-site.

The easy-to-use Vaisala HM40 is a compact and portable humidity meter that provides reliable measurements in a wide range of applications. It is the ideal spot-checking tool for everything from structural moisture measurement and air conditioning systems to humidity measurement in industrial production processes and life science applications. The HM40 has a large, user-friendly graphical display and easy-to-use push buttons. In addition to relative humidity and temperature, the HM40 provides five calculated humidity parameters, all of which are available in metric and non-metric units. Included in delivery is a certificate of calibration which is traceable to national and international standards. There are four different models available: HM41, HM42, HM45, and HM46. Calibrating the HM40 is easy. The meter or the probe can be sent to a Vaisala Service Center for recalibration. Alternatively, calibration can be completed on site by users with a humidity reference such as the...

The DK660 CO2 data logger is a robust device for logging CO2, humidity and temperature. It features one of the latest state-of-the-art NDIR sensors and provides precise readings through the range of 0...2000 ppm (optionally 5000 ppm or 1%). Thanks to the low power consumption of the DK660 continuous measurements of up to 2 years are possible before the battery needs to be replaced. Its internal real time clock allows for time-referenced synchronizing of several devices. Each CO2 logger comes with a declaration of conformity. A certificate of calibration can be included in delivery on request.
