The external form dimensions (mm) body: Φ 90*53mm (I include a rubber protector) probe: The Φ 43*170mm weight (g) body: Approximately 290 g (I include a battery, a rubber protector) of probes: I can minimize the difference with the hand analysis by letting you memorize the immediate absorbance that gathered approximately 510 g (include a cable) of deployment correlation-type one kind of feature, sludge water, and doing proofreading (back proofreading) when I knew a hand analysis level. ・The minimal wound of the deterioration and cell side of the source of light can revise it only with tap water by putting a narrow gap cell and the law of the Lunt vent bell together without using a proofreading board. ・The services such as repair guarantees are received for five years when I have you enroll in "reliable pack" (paid separately) at the time of the purchase. Specifically, please refer. ・Of IP67-proof; pitch a camp, and is waterproof structure. ・The rubber protector of the shock absorption function includes it. Specifications function: Measurement system built-in in one kind of correlative expression: 　MLSS measurement infrared rays pulse transmitted light method. An indication method: The digital liquid crystal display measurement range: 0-9990 mg/l (10 mg/l of smallest resolving power), 10,000-20,000 mg/l (100 mg/l of smallest resolving power) of automatic range change plasticities: 　Less than ±2% (constant condition) of the instructions level 　It is a proofreading method (as for less than 5,000 mg/l less than ±150 mg/l): 　MLSS measurement zero proofreading: The tap water proofreading with the proofreading container. 　　Two points of proofreading: Zero proofreading and proofreading in MlSS 濃度既知検水. 　　Three points of proofreading: Proofreading with zero proofreading, MLSS 濃度既知検水 and the 1/2 dilution water. A use temperature range: The 0-40 degrees Celsius cable head: A 2.5m (as standard equipment) power supply: Single 4 form alkali dry cell *3 (DC4.5V)
