Corning 6795-400D PC-400D Hot Plate, Digital Display, 5" x 7" Pyroceram Top, 7.75 x 4.25 x 11" (L x W x H), 5 to 550 Degrees C, 120V/60Hz

The higher the temp goes the further its off, at 35C its pretty close. In order for me to get it up to 244F i had to set it to 160C. So it's definitely not a scientific instrument. I would send it back if i had not waited past the return date.edited after reading manual, right there in the manul it says there will be variances.so a temp set at 250C will be 205C

Use in our lab - excellent temp control. 5 degree increments.

It's been one year and i am very happy with this hot plate. The digital display is perfect, no guess work on how hot your surface is. Heats up very quick and Amazon got the best price compared to fisher scientific or any other rip off lab supply companies. Did I mention this is great for my Bialetti stove top coffee maker too?

This item is sold as a "scientific" lab quality hot plate at a premium price. The digital thermostat is grossly inaccurate, when set at 175 F the center of the plate read 154F consistently and as the plate was scanned with a digital thermometer the edge of the plate read 54F ....... consistently, absolutely no thermal uniformity! When a request was made for a return label, the merchant insisted it was an anomaly and a replacement would be shipped along with a return label for the original unit. I suggested they test the new unit prior to shipment ........... the new unit was never received and after considerable correspondence and hassle, a ship label was received via email and my account was credited.

Quick shipment. As described in listing. Better design if liquid being heated overflows.

Works kinda pricy tho

Perfect for what we needed it for, controlling cooking tomjustbunser boiling.

Thank you!!

No so precise but stable.

Did not meet expectations
