Hanna Instruments HI839800-01 COD Test Tube Heater, 25 Vial Capacity, 115V, +/-2 Degree C Accuracy, 7-1/2" Length x 11-51/64" Width x 3-11/16" Height

COD reactor is constructed of durable materials. The aluminum block incorporates a 25-vial capacity and a well for a reference temperature probe. The COD reactor is an easy to use test tube heater. Its well-marked user interface provides intuitive operation. The reactor is equipped with two predefined temperature settings: 150degree and 105degreeC. COD and total phosphorus digestions are conducted at 150degreeC, and total nitrogen digestions are at the 105degreeC. In addition, it has 3 LED’s for visual indication. A green LED indicates power, a blinking red LED warns the user of a hot heater block (above 50degreeC), and a yellow LED indicates heating. A three hour countdown timer is also incorporated to control timed digestions. When the countdown timer expires, a beep will sound and the heating element will turn off. The reactor contains a thermal fuse that prevents overheating by turning off the heating element. Block temperature is continuously displayed on the LCD even when there is no active temperature program running. It is supplied with power cable and instructions. Temperature of reaction: 105 degree C or 150 degree C (221 degree F or 302 degree F). Temperature Stability: +/-0.5 degree C (+/-0.9 degree F). Temperature range: -10 degree C to 160 degree C (14 degree F to 320 degree F). Accuracy: +/-2 degree C (+/-3.6 degree F). Capacity: 25 vials (16mm diameter by 100 mm height), one receptacle for a stainless steel reference thermometer. Warm-up time: 10-15 minutes, depending on selected temperature. Operating mode: timed (0 to 180 minutes) or infinity mode. Block: aluminum. Environment: 5 to 50 degree C (41 to 122 degree F). Power supply (fuse protected): 115 VAC; 60 Hz; 250 W. Measure 7-1/2" length by 11-51/64" width by 3-11/16" height.
