What kind of measurement precision loss can I expect after using for some time?
The circuitry in the device has been designed to withstand the effects of changes in the surrounding environment and changes in electrical properties; therefore the precision of the measurements does not degrade over time.
Although the sensor element of the temperature sensor does not experience loss of precision due to use over time, due to external factors, such as build up of water, losses in precision will occur. If you find that measurements are becoming less and less precise, we suggest changing the sensor. Humidity sensors will also lose precision due to water and dust buildup.

What does Thermal Time Constant mean?
This is an estimate of response time based on JIS standards.
It is the amount of time it takes for the 63.2% of the temperature measurement to be reached.

Is it possible to use some kind of sensor extension cable?
The maximum length and compatible extension cables vary depending upon which logger is being used.
See below for details.
【TR-71nw, TR-71wf, TR-701NW, TR-701AW, TR-71W, TR-71Ui, TR-71U, TR-71S】
Compatible Extension Cables: TR-1C30 (3m), TR-5C10 (1m)
Up to 3 meters of extension cables can be used per sensor.
【RTR-502, TR-52i, RTR-71, RTR-52/52A, TR-52S, TR-52】
Compatible Extension Cables: TR-2C30 (3m)
Up to 3 meters of extension cables can be used per sensor.
【RTR-505-Pt, TR-81, RTR-52Pt】
There are no separate extension cables for these loggers, but T&D order-made Pt100 sensors come in various types and lengths of up to 99 meters. If a long cable is necessary we strongly suggest using one of these logger models.
Note that Pt100 sensors are produced only upon receipt of order; therefore please allow four weeks from the time of order until shipping.
【TR-73U, TR-72W, TR-72Ui, TR-72U, TR-72S】
Temp-humidity sensor cables over 1 meter cannot be used for the above models.
The TR-3100 sensor supplied with TR-73U, TR-72Ui and TR-72U can use the extension cable TR-5C10 (1m). Note that the temp-humidity sensor TR-3110 with 1-meter cable cannot be extended.
If you are using an optional temperature-only sensor, up to 3 meters of extension cables can be used per sensor.
Compatible Extension Cables: TR-1C30 (3m), TR-5C10 (1m)
【TR-72nw, TR-72wf, RTR-574, RTR-576, TR-74Ui, TR-76Ui, TR-702NW, TR-702AW, TR-77Ui】
Compatible Extension Cables: TR-1C30 (3m), TR-5C10 (1m)
Up to 9 meters of extension cables can be used per sensor.
【RTR-507, RTR-505, TR-55i】
Compatible Extension Cables: TR-3C30 (3m)
Up to 3 meters of extension cables can be used per sensor/module.
【RTR-503, RTR-72, RTR-53/53A】
Extension cables cannot be used with these models.
