With our highly accurate, compact design, TE has set the standard for top–quality environmental monitoring instruments. Now our next generation of data logging transducer models – the TruBlue 275 BARO – combines precision, performance, and rugged reliability like no other instrument available today. Designed to deliver time and time again in even the harshest conditions, the TruBlue 275 BARO is battery powered and made with 316 stainless steel or titanium. A fully sealed design and advanced, power-conserving microcomputer technology enables it to log baro-metric pressure and temperature for up to ten (10) years. Since these units do not require onsite power or a programmable logic controller (PLC), a terminal box isn’t necessary. The TruBlue 275 BARO is the perfect choice when reliability, accuracy and precision are needed in a compact, competitively priced design.
