产品描述：
The Grant QBH2 is a programmable high-precision dry block heating system with two removable/interchangeable blocks for applications requiring higher temperatures.
Digital temperature control for optimum precision
Heating range ambient + 5º to 200ºC*, with rapid heat-up time
Stability and uniformity ± 0.1ºC
Programmable
Features
High power heater for fast heat-up – 25º to 100ºC in only 20 minutes.
Simple-to-use rotor plus two keys provide access to the interactive interface for fast, accurate set-up
Clear digital display – easy to read from a distance for instant reassurance
Convenient timer facility, with audible buzzer, for reaction timing and function timing, e.g. delayed heater switch-on/turn-off
Wide range of interchangeable blocks enables you to mix and match sample tubes as desired – extraction tool supplied as standard for easy and safe removal of blocks.
Three programmable temperature/time segments plus end-of program segments
Optional safety cover – protects samples from contamination and users from accidental contact with hot blocks
Overtemperature cut-out protects your samples and your workplace
High quality, robust construction in streamlined coolwall aluminium and chemical-resistant plastic – durable in demanding environments
Compact footprint to optimise use of benchspace
