PB-607APortable intelligenceDissolved oxygen analyzer(Hereinafter referred to as the instrument), mainly for the convenience of the user to carry to the site operation and design. The instrument can be divided into two parts, the sensor and the electronic unit. The sensor film type polarographic oxygen electrode. The electronic unit is a high integrated circuit. The instrument uses dot matrix liquid crystal display, which can display the value of dissolved oxygen and temperature. Two, technical parameters Main features: Dot matrix backlight LCD display Automatic temperature compensation, fast response time Portable, easy to carry With the factory dissolved oxygen electrode (a type of film coated with the film type) Main technical index: 1.Measurement range: Dissolved oxygen:(0~20) mg/L temperature Degree:(0~40)DEGC 2Basic error: Dissolved oxygen0.3mg/L temperature Degree: + +1DEGC 3Residual current: no more than0.15mg/L 4Response time: no more than30s (20DEGCtime90%response) 5Automatic temperature compensation range:(0~40)DEGC 6Electric Source:7No. four alkaline battery 7Shape dimensionMm):180*80*30 8Heavy The amount of:1kg
