Latest cooling system reduces negative factor to global environment. With ambient
temperature at 35℃, while temperature of inside chamber maintains -30℃.
■ PCM structure
PCM structure reduces amount of organic solvent.
■ Temperature control function
Unified temperature control range for same categories realized to set -20℃, which
is suitable for reagent preservation.
■ Specification unified
Unified specification for same categories, which also realized to unify performance for
high/low temperature alarm (SV is changeable in the range ±5～±15℃), power failure
alarm, remote alarm terminal, setting memorization by non-volatile memory.
Adopt new microprocessor system for display panel and keypad makes operation easily.
