Vaisala PTB330 Barometer

The Vaisala PTB330 digital barometer is a new generation barometer designed for a wide range of high-end atmospheric pressure measurement. Featuring a silicon capacitive, absolute pressure sensor, the PTB330 features extremely high accuracy.

According to customers' needs, the PTB330 can incorporate one, two or three BAROCAP sensors. When two or three sensors are used, the barometer continuously compares the readings of the pressure sensors against one another and provides information on whether these are within the set internal difference criteria. This unique feature provides redundancy in pressure measurement. Thus, users get a stable and reliable pressure reading at all times as well as a pre-indication of when to service or recalibrate the barometer.

The PTB330 barometer comes with a NIST traceable, factory calibration certificate, also optional ISO/IEC 17025 accreditation calibration services are available.

Vaisala MI70 Hand-held Indicator

The Vaisala Measurement Indicator MI70 is a user-friendly indicator for demanding spot-checking measurements. It is ideal for field checking and calibration of Vaisala's fixed instruments.

The MI70 features a multilingual, menu-based user interface, and a clear graphical LCD display. Overall three measurement parameters can be displayed and logged into the meter's memory at the same time. One or two probes or transmitters can be connected simultaneously.

The optional MI70 Link Windows software and the USB connection cable form a practical tool for transferring logged data and real time measurement data from the MI70 to a PC.

Vaisala HPM155 Humidity and Temperature Probe

The Vaisala HMP155 HUMICAP humidity and temperature probe provides reliable humidity and temperature measurement. The HMP155 has excellent stability and can withstand harsh environments well. The probe structure is solid and the sensor is protected with a sintered teflon filter, which gives maximum protection against liquid water, dust, and dirt. What's more, with its fast response time, the additional temperature probe for the HMP155 is ideal for measurement in environments with rapidly changing temperatures.

The Vaisala HMP155 sensor is NOT included with the PTB330TS and must be purchased as an accessory.
