Please see the photos attached of the old PakTronics PakStat with a 1000-ohm sensor.
nSpire Touch or nSpire Touch Wifi can be used as a replacement since they allow to select a custom sensor type and enter ohm values for the requested temperature level.
When setting up the custom sensor option on UDG4/UWG4, use the following values interoplated from the attached chart below:
- 1059 ohms for 59F
- 1080 for 68F
- 1097 for 77F
- 1116 for 86F
See the chart attached.
