Heating elements in all three walls, bottom, and door create a warm air jacket around the inner chamber to guarantee superior temperature uniformity with no hot spots. Warm air jacket design also provides quick temperature recovery—and there’s a full-length inner glass door for viewing specimens without disturbing the chamber atmosphere. No need to worry about heater element damage from spills either—the inner chamber is tack-welded, and the low-watt density heating elements are safely isolated from the work chamber.

Microprocessor controlled for easy keypad set and calibration. Temperature display may be calibrated to match a secondary thermometer. For over-temperature protection, a second, independent safety controller can be preset and has visual alarm when activated. All units are stackable without the need for spacer racks. Features through-wall access port for chart recorder. A UL-approved, vapor-tight electrical outlet is inside the sealed chamber. Adjustable leveling feet compensate for uneven surfaces. Shelves adjustable in 1.3cm (¹/₂") increments.

Description:

The 2100AN laboratory turbidimeter measures turbidity in NTUs (nephelometric turbidity units), NEPs (nephelos) and EBCs (European Brewing Convention units). NEPs and EBCs are calculated using the conversion factors of 6.7 nephelos per 1.0 NTU and 0.245 EBCs per 1.0 NTU. The 2100AN turbidimeter also measures absorbance, transmittance and color (APHA Pt-Co Method). The turbidimeter has a built-in printer and an RS232 output for connection to a printer, data logger or computer and a recorder output. The turbidimeter contains a real-time clock with battery. The clock provides a time-date stamp on all data transmitted to the built-in printer or to external devices by way of the RS232 interface (i.e., measurements and calibration records).
