Technical highlights of the testo 6681 climate transmitter

• High-quality digital probes available for the temperature/humidity transmitter: e.g. high-precision Testo humidity sensor with long-term stability, probe for high-humidity measurement, probe for trace humidity measurement, probe with a self-monitoring function (for measuring in sensor-damaging media)
• Smart probe technology: probe can be changed by the user, digital interface for the temperature/humidity transmitter, intelligent calibration concept
• Ethernet, relay and analog outputs allow for versatile use of the temperature/humidity transmitter: e.g. for control purposes (2 or optionally 3 analog outputs), for direct activation of units in the air conditioning system (optionally via relay) or even in climate monitoring systems (optionally via Ethernet connection)
• P2A software for parametrization, adjustment and analysis saves time and money during commissioning and maintenance
• Optimum protection: the temperature/humidity transmitter features a robust metal housing and is protected against water jets according to protection class IP 65. Protective caps are also optionally available for specific applications (made of stainless steel, PTFE, wire mesh filter or metal). A patented H2O2 protective cap is also available to order
• 2-line display: the climate transmitter is optionally available with a display, enabling you to undertake commissioning, adjustment and analysis without using a PC
• Options for self-monitoring and early warning function: guarantees high system availability
