User questions & answers

Question:	Does this thermometer comes with a current up-to-date calibrator certificate
Answer:	It was good for about 20 months
Question:	Can you download the temp logs to your pc via USB or flash drive? How long does it keep logs? 30 days or is it less
Answer:	This version does not have the capability of transferring the info to a USB or flash drive. We keep paper logs at our facility, so we manually recorded.
Question:	Is the bottle made of glass
Answer:	Yes. I've seen some with plastic and the readings aren't as accurate. I'm not sure if there was a different reagent in the bottle or if the material played a part in that though.
Question:	Is there a warrenty with this item
Answer:	It depends on what warranty means. Each thermometer comes with a traceable certificate of calibration which is good for 2 years. You can have these thermometers recalibrated if needed by the company

User questions & answers

Question:	Is the display visible when not using the backlight
Answer:	Yes but poorly when you use the backlight, and it depends from what angle you are viewing it. It is excellent looking down on it from more than 10 degrees. Looking directly at it it is 90% visible. As you tilt it backward it rapidly becomes unreadable (looking up at it). I bought this to put on the wall of my rv and the backlight was completely useless
Question:	Where can I find the manual
Answer:	The unit that I received was the TP-65S. PDF version of this manual can be found here: https://buythermopro.com/wp-content/uploads/2018/06/Thermopro-EN-DE-FR-IT-ES-TP-65S-instruction-manual-20180503.pdf
Question:	Can this be set so that it doesn't scroll through all three sensors? i only have one sensor and i'd like it to simply display that outdoor temp
Answer:	I never had a problem with that. My only problem is the remote sensor is registering the wrong temperature. When I suspected this, i brought the monitor in and put it side by side with the main unit. Was off 4 degrees. My AC thermostat said 74, the main ThemoPro unit said 74, but the remote sensor was transmitting 78 degrees. So it's pretty much useless for what I bought it for.
Question:	how far away will the remote sensor read back to the unit
Answer:	The promotion materials on the Amazon website indicate 200'; with good penetration of walls, etc. Our sending unit is located about 50' away from the receiver; hung under a carport to better protect it from the weather; and the signal must penetrate a brick wall to enter the house. We are extremely pleased with it; particularly the large display and back-lighting features; which make it easy to read from across the room by a visually-impaired person. It will probably live up to the 200' straight-line distance claim; but might be affected by obstacles in the line-of-sight; such as parked cars, trees, walls, etc. Hope this is helpful.
