Title: CDN NSF Heavy Duty Oven Test Thermometer
Review: Purchased this item to check my oven temperature as it is NSF rated thus I concluded it was very percise. Placed same in my Jenn-Air Oven (4 yrs old) and set oven temp @ 350 degrees F - after oven came to temp CDN thermometer read 325, thus I increased oven temp to 375 after temperature had stabilized CDN thermometer read 340. At this point I utilized my Polder remote thermometer normally used for roasting meat and placed the remote probe next to the CDN thermometer after stabilizing the Polder recorded a temperature of 370 to 387 depending if the gas burner was ignited. The CDN thermometer continued to read 340 - 345. Very disappointed in the accuracy and performance - thumbs down!
