Microscopic precision temperature controller
|
|
The working temperature can reach up to 300 ℃ under a 20x objective lens, and the temperature operation program is fully automatically controlled; The temperature program segment is set by the user themselves, with 30 temperature programming segments and cyclic operation, which can accurately reflect the set temperature, furnace core temperature, and actual temperature of the sample. Set the starting temperature for each segment, and the duration that can be maintained within that segment. The heating rate can be adjusted, with an accuracy of ± 0.3 ℃ and a memory point reading
Microscopic heating platform
It can move with the stage, has a large heating area in the working area, adjustable transparent area, and a temperature gradient in the working area below ± 0.1
