PTB330TS transport case

Barometric Pressure Transfer

Standard PTB330TS makes eld

inspection accurate and easy. It

combines a PTB330 digital barometer

with a hand-held MI70 indicator

within a portable unit functioning

as a transfer standard. The optional

HMP155 probe is available for

accurate humidity and temperature

measurement.

The PTB330TS is suitable for various

reference measurements in industrial

and meteorological areas.

The PTB330TS comes in a durable

and weatherproof transport case

that can be easily carried and

shipped. The components are placed

in a proong foam interior, with

accessories and user’s guide placed

in the lid organizer. The case includes

a separate inner tabletop case in

which the barometer is mounted.

Shoulder strap is included for

convenience. Battery duration is up

to 11 hours of continuous use and up

to 30 days in data logging use.

PTB330 Digital barometer

Vaisala BAROCAP

Digital Barometer

PTB330 is a new generation

barometer designed for a wide

range of high-end atmospheric

pressure measurement. The pressure

measurement of the PTB330 is based

on the Vaisala in-house, silicon

capacitive, absolute pressure sensor

– the Vaisala BAROCAP

Sensor. It

provides high measurement accuracy

and excellent long-term stability.

High accuracy

The PTB330 series features extremely

high accuracy. Class A barometers for

the most demanding applications are

ne-adjusted and calibrated against

a high-precision pressure calibrator.

All the PTB330 barometers come with

a NIST traceable, factory calibration

certicate, also optional ISO/IEC

17025 accreditation calibration

services are available.

Reliability through

redundancy

According to customers’ choice, 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

The PTB330 Digital Barometer

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 re-calibrate the

barometer.

Optional HMP155

Humidity and

temperature probe

The new Vaisala HUMICAP

Humidity

and Temperature Probe HMP155

provides reliable humidity and

temperature measurement.

Long-term stability

The HMP155 has a new generation

Vaisala HUMICAP

180R sensor

that has excellent stability and

withstands harsh environments well.

The probe structure is solid and the

sensor is protected with a sintered

teon lter, which gives maximum

protection against liquid water, dust,

and dirt.

Fast temperature

measurement

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.

MI70 Hand-held indicator

for spot-checking

applications

The Vaisala Measurement Indicator

MI70 is a user-friendly indicator

for demanding spot-checking

measurements. It is ideal for eld

checking and calibration of Vaisala’s

xed instruments.

Easy-to-use user interface

and three-variable display

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.

MI70 Link

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.
