Dissolved oxygen analyzer
1、 Technical features
At home and abroad, the host core adopts 32-bit computer and arm system, which realizes high reliability, high precision, high speed and convenient function expansion. Users can fully enjoy the subsequent value-added services.
1) Super small, easy to carry and operate.
2) Simple eight key position, with backlight adjustment.
3) 128 × 64 super durable LCD screen, Chinese / English menu, easy to learn and remember.
4) It meets the IP55 international protection standard and can work reliably in various harsh environments.
5) There are two types of electrodes, common type and precision type, which can be used in two ways: flow cell type and sink type.
6) Equipped with rechargeable lithium battery, super long standby time, with battery capacity, charging and discharging status display.
7) The electrode structure is firm. Simple maintenance and low maintenance cost.
8) No need to calibrate zero point, no drift.
2、 Technical indicators:
1) Range: automatic switching of instrument (0 ~ 20) μ g / L (0 ~ 200) μ g / L (0 ~ 20) mg / L
2) Basic error: 1.5% F.S
3) Repeatability: ± 0.5
4) Stability: ± 1.5 × 10-2 / 4H
5) Response time: 98% f.s/25 ℃ within 30s
6) Temperature range: 0 ℃ ~ 99.9 ℃
7) Instrument resolution (temperature): 0.1 ℃
8) Temperature compensation range: ± 2%
9) Power supply and power: AC: 220V ± 22V, 50 ± 1Hz, 5VA (built-in dc3.7v rechargeable lithium-ion battery, rechargeable by USB)
