Page 15: Chapter 2 Product Overview
Chapter 2 __________________________________________________________ Product Overview CHAPTER 2 PRODUCT OVERVIEW This chapter introduces the features and advantages of Vaisala ® HUMICAP Humidity and Temperature Module HMM213. Introduction to HMM213 The HMM213 modules are designed especially for relative humidity measurements in environmental chamber applications with high temperature and humidity levels. - Page 16 USER'S GUIDE____________________________________________________________________ The HMM213 modules are connected to process control systems with screw terminals. These versatile modules incorporate the ® HUMICAP 180R humidity sensor, which uses an operating principle based on changes in the capacitance of a thin polymer film as it absorbs water molecules.

Page 17: To Be Noted When Measuring Humidity
The ® HUMICAP 180R sensor returns to its normal functioning as soon as water has evaporated. Contaminated water condensing on the sensor may shorten its life span and alter the calibration. VAISALA _______________________________________________________________________ 17... -

Page 31: Chapter 6 Calibration
CALIBRATION This chapter contains information that is needed to calibrate this product. Vaisala recommends a recalibration of the HMM213 module after six months of use. After the first recalibration, the recommended calibration interval is approximately 12 months. However, please note that these intervals depend on the operating conditions and the required accuracy. -
Page 32: Humidity Calibration
A one-point calibration can be done against an accurate transfer standard in the field and a two-point calibration using saturated salt solutions in controlled conditions (HMK15). You can also send the instrument to Vaisala or a Vaisala representative for recalibration. Humidity Calibration with Serial Commands Two-Point Calibration CRH <cr>... -
