Protected display
Scratch-resistant, recessed and with a special, replaceable protective film.
Secure mounting
4 strong magnets with rubber coating – particularly material friendly.
Robust sensors
Extremely durable O2 sensor, automatic dilution up to 30,000 ppm CO.
Paper-free documentation
Create measurement reports (incl. measurement value, location, customer data) directly on site, with comments, customer’s signature and e-mail dispatch.
Truly flexible
A flue gas analyser perfectly tailored to your needs: Flexible configuration with regard to the sensors and their warranty period, versatile probes and an interface to common sector Apps and software applications.
Examples
Flexible instrument configuration
Choice of 2-year or 4-year warranty for the sensors. Additional slot for NOx sensor (besides O2 & CO sensor).
Versatile probes – quickly changed
A variety of probe shafts can easily be attached to the multi-functional handle.
Tried-and-tested probes
The testo 320, testo 330 and testo 330--1/-2 LL probes with their practical multi-plug are also suitable for the testo 300.
New probes
New probes with reversible USB-C connection are available for temperature measurements, for example flow and return temperatures, along with ambient CO measurement.
The interface to the future – Testo connectivity
Transfer measurement data quickly and easily to common sector Apps and software applications wirelessly by WLAN and Bluetooth. More information.
"My very first test of the new flue gas analyser testo 300 showed me that with the newly introduced technology, it’s made a giant quantum leap."
Marcello Cigoli, Italy
"The built-in address book of the testo 300 is among our favourite features. Now every customer is listed with which measurements were done, with which results."
Erwin van de Pol, Netherlands
"I especially like the user-friendliness of the testo 300. If you can handle a smartphone, this measuring instrument is right for you."
Sebastiaan Moonen, Netherlands
"The testo 300 makes the same robust impression on me as the testo 330-2 LL already did. But with the new display, there’s a lot which is more user-friendly and easier to operate."
Maximilian Kretschmar, Germany
