Vintage Scientific Products Temp Blok Module Heater Heat Block

Up for sale is a vintage Scientific Products (S/P) Temp-Blok Module Heater Incubator, Dry Bath. It comes with a heat block / heating block. I plugged it in for 10 minutes and it heated up. However, I do not have the proper equipment to fully test it out, so it will be sold as is, no returns. The model number is H2025-1. Overall in excellent cosmetic condition except some surface rusts. Thanks!

Specs:
* Temperature up to 150 °C
* Analog low temperature/high temperature controls
* Accommodates one standard size heatblock (included)
