This versatile instrument provides calibrations from 1-30 inHg vacuum (0.03-1 bar) and 3-500 psi (0.2-35 bar) in one extremely accurate yet easy to use primary standard. A selector valve converts the unit from pressure to vacuum mode without the need to exchange pistons. Units are manufactured to the highest standards with certified accuracies traceable to International Standards Laboratories such as the National Institute of Standards and Technology (NIST). These piston/cylinder type pneumatic standards provide excellent stability, repeatability and accuracy. An optional built-in hand pump can be added for both pressure and vacuum generation.

Key features
• 0.015% of reading accuracy standard (0.008% optional)
• 1-30 inHg vacuum (0.03-1 bar vacuum)
• 3-500 psi (0.2-35 bar) pressure
• inH2O and mbar ranges available
• Series 3 non-magnetic stainless steel weights
• Units can be trimmed to local gravity FOC

The three models of the new 170 Series are the new benchmark for common multimeters. All three set the standard with their combination of precision, features, ease of use, safety and reliability

• Be aware of voltage easily - the tip glows red and a beeper sounds when voltage is detected

• Continuous self-test so you always know it’s working

• Voltage detection range for wide application use - 90 V to 1000 V AC or 200 V to 1000 V AC

• Audible/Silent mode for added convenience

The testo 350 is a rugged, easy-to-use exhaust gas analyzer designed to meet the highest demands when it comes to carrying out precise industrial emission measurements and providing proper data administration. The Analysis Box can be operated with up to 6 gas sensors, 5 of which are optional. This allows you to select freely from sensors for CO, NO, NO2, SO2, H2S, CxHy and CO2.

Your advantages
• Increased measurement range for unlimited measurements even when gas concentrations are higher
• Easy-to-change gas sensors and easy access to wearing parts
• Sealed housing with built-in impact protection for use in harsh conditions
• Easy operation of the analyzer unit via Control Unit or easyEmission software (both products available separately)
