accurite thermometers not so accurate

[packerfan79]

So I picked up an accurite digital thermometer to check my temps. My plants are cool to the touch but it's reading 91. This is the second accurite digital thermometer to be significantly off. Has anybody else had this problem? Where the hell can I get a thermometer that works her. I hate wasting hard earned cash on crap

I've had good success with Springfield Precise gauges. $6 Walmart.

Gauges cannot be directly in the light path; need to be offset, in the shade.

Cool wizard thanks. Moved it to a shady spot now its reading right I think temp dropped 14 degrees in 5 min.

i have acurite/aculink wireless weather station and sensors placed all around my flower/veg rooms and they work accurate. All three monitors in different rooms and locations all read near same, i have hardwired temp/rh sensors placed all around in each room and they as well are giving me the same readings, the cool thing about the aculink, I can go out or be out of state and just go online and see what my rooms conditions are like, this combined with a few other goodies and a autopilot master atmospheric controller with the usb computer plug in, lets you control your room from any location as long as you have internet, you can be hundreds of miles away but be able to log on the comp and switch your conditions by turning on or off equipment, fans, lights, co2, ect.

Unless you need data logging , the cheapest and most accurate are old mercury or alcohol medical types.

The ones in pH meters were several degs out in the three I have owned.

An old thermometer and narrow range pH strips are as accurate as digital equivalents but cannot drift and need no calibration , worth the slight inconvenience in use.
