A wide range of models is available with working temperature ranges from +48° to -69°C. Each multi-bath unit conforms to ASTM D97 Pour Point and ASTM D2500 Cloud Point test methods and related methods. Each stainless steel liquid bath has its own digital indicating PID temperature controller with 0.1°C resolution, providing temperature stability of ±1.5°C. The baths of select models are agitated for improved temperature stabily (±0.5°C) and uniformity and are, therefore, suitable for ASTM D6371 (or IP309) cold filter plugging point test with the addition of the CFPP kit. Each bath comes equipped with 4 metal test jackets, 4 cork rings, 4 O-rings, and 4 cork stoppers for the thermometer (test tube is available separately). All units are mechanically refrigerated using ozone friendly non-CFC and non-HCFC refrigerants.

Model 334 is the most popular and versatile 3 bath bench model is the "work horse" of the industry. The baths are factory preset at 0°, -18°, and -33°C. Each bath has 4 test sample capacity. The approximate overall dimensions are 25 x 19 x 26 inches high (62 x 48 x 65 cm).

Model 335 is very similar to Model 334 but with the -33°C bath agitated for temperature stability (±0.5°C) suitable for ASTM D6371 (IP309) CFPP test.

Model 644 is also a popular caster mounted, floor model with 4 baths factory preset at 0°, -18°, -33°, and -51°C. Each bath is mechanically agitated for improved bath temperature uniformity and control. Each bath has 4 test sample capacity. Approximate overall dimensions are 37 x 31 x 43 inches high (94 x 78 x 110 cm.)

Model 654 is a caster mounted floor model with 5 baths factory preset at 0°, -18°, -33°, -51°, -69°C. Each bath is mechanically agitated for temperature stability of ±0.5°C.

Model 549 is a single liquid bath apparatus with 4 sample test capacity, adjustable from 0° to -69°C. Its temperature stability is ±1.5°C. It is an economical choice for those laboratories with samples with extra low temperature pour point samples.

Model DR-2L with two test positions is a portable, unique cloud and pour point bath, not using any liquid as the cooling medium. It has the ability to very rapidly (less than 2 minutes) change the metal cup temperature to the next lower temperature. This allows one bath to perform the pour and cloud point as well as CFPP tests without the need to move the test tube to the next lowest bath temperature. Each cup has its own digital temperature controller and their temperature may be set independently. Lowest bath temperature is -69°C.

Model DR-1H/L is similar to Model DR-2L and is an economical, compact single test position bath with lowest bath temperature of -33°C. It is an ideal bath for mobile fuel testing laboratories. Overall dimensions are 22 x 18 x 33 inches high (55 x 45 x 83 cm).

Model 620 is a 20 test sample capacity in each of the 3 baths preset at 0°, -18°, -33°C. It is intended for those laboratories with a very high volume of test samples.
