Datasheet What to ask when choosing an instrument? Buy Now Handheld Moisture and Temperature Meter for spot-checking in oil MM70 for transformers and oil pipelines Reliable MM70 is an ideal tool for the preventive maintenance of oil-filled systems. The water activity measurement indicates the margin to free water formation, which causes severe problems in lubrication systems. Excellent pressure and temperature tolerance. The probe can be inserted directly into the process pipe through a ball valve without draining the oil in the system. The MM70 also supports the use of Vaisala's humidity, dew point, and carbon dioxide probes, making it a versatile investment applicable to several multi-parameter applications. Two probes can simultaneously be connected to the MM70. The optional MI70 Link Windows® software in combination with a USB connection cable is used to transfer logged data and real time measurement data from the MM70 to a PC. Download free MI70 Link Windows® software here. Features Measurement independent of oil type, age and temperature - indicates margin to oil saturation In-line process checking through ball valve, no need to drain the oil Rugged and reliable construction Multi-probe operation; dewpoint and CO2 probes can also be connected Vaisala HUMICAP® Sensor - proven field performance since 1973 + Show more Key Benefits Convenient No reference oil needed for recalibration. Easy in-line process checking No need to drain the oil. The probe can be inserted directly into the process pipe through a ball valve without draining the oil in the system. Cost-effective multi-probe operation Supports the use of Vaisala's humidity, dew point, and carbon dioxide probes, making it a versatile investment applicable to several multi-parameter applications. One or two probes can be connected simultaneously.
