–Performs two
tests at 75°F (24°C) and two tests at 200°F (93.5°C). Consists of two 12x18"
(30.5x45.7cm) constant temperature baths with 1000mL test cylinders, certified
diffusers, air delivery tubes, and flowmeters (94mL/min.) for each sample.
Baths are equipped with microprocessor temperature controls, copper
immersion heaters and 1
⁄20hp circulation stirrers to maintain temperature
uniformity of ±1°F (±0.5°C). Microprocessor PID control provides quick
temperature stabilization without overshoot and the bath is protected by an
overtemperature control circuit that interrupts power should bath temperature
exceed a programmed cut-off point. Dual LED displays provide actual and
setpoint temperature values in °C/°F format. Test cylinders are held securely in
place by quick-locking cams in the bath cover assembly. A separate stainless
steel support rack is provided to hold the test cylinders after removal from the
bath. Cold bath (24°C) has built-in coils for circulating exit air from the high
temperature test cylinders prior to passing to a volume meter, and a separate
coil for circulating cooling water or refrigerant when the ambient temperature
exceeds the test temperature. Supplied with rubber stoppers and glass air
outlet tubes for each cylinder. Bath controls are enclosed in a finished steel
base with chemical resistant polyurethane enamel finish. Communications
software as seen on page 110 (RS232, etc.), ramp-to-set and other
enhanced features are available as extra cost options. Contact your Koehler
representative for information.
