AVT Reliability® do not provide a spare MSM-01 sensor when sites MSM-01 is in for calibration or repair.
AVT Reliability® recommend purchasing a spare sensor for scenarios like this. If the sensor is out of of charge or has been sent off for calibration or repair, it is handy to have a spare sensor so you can continue your condition monitoring activities.
That said our team are fully prepared to test and return sensors as quickly as possible to reduce the impact of this.
