Dissolved Oxygen Meter Gauge Water Quality Tester with 3.5m Probe DO Range 0 to 30mg/L Accuracy ±3% Data Recording

QIUSUO Dissolved Oxygen Meter Gauge Water Quality Tester with 3.5m Probe DO Range 0 to 30mg/L Accuracy ±3% Data RecordingIntroduction:Batteries and Liquid are not included in the package！！！Dissolved oxygen meter is used to measure the dissolved oxygen content in the aqueous solution of the measured sample in the field or in the laboratory Since dissolved oxygen is one of the main indicators of the quality of water, dissolved oxygen electrodes can be used in a wide range of applications to measure dissolved oxygen content, especially in cultured water, photosynthesis and respiration, and in the field. When assessing the ability of streams and lakes to support biological survival, biochemical oxygen demand (BOD) tests are performed to measure and determine the relationship between dissolved oxygen concentration and the temperature of the sample water solution as the oxygen-consuming sample water solution containing organic matter becomes putrefied.Technical parameters♣ Dissolved Oxygen Measurement Range：0.0~30.0(mg/L) ♣ Dissolved oxygen resolution：0.1(mg/L) ♣ Dissolved Oxygen Accuracy：±3.0% Full range ♣ Dissolved oxygen calibration：Air 100% saturated dissolved oxygen correction ♣ Temperature Measurement Range：-5°C~60.0°C ♣ Temperature Separation Rate：0.1°C ♣ Temperature Accuracy:±0.5°C ♣ Temperature unit switching:℃/℉ ♣ Recorded data:Manual recording 99 groups ♣ Salinity compensation:0~42ppt ♣ Altitude compensation:0~3500m ♣ Automatic Temperature Compensation ATC:√ ♣ Automatic shutdown:After 1 hour without operation ♣ LCD size:38×54mm ♣ Backlight:√ ♣ Probe line length：Approx. 3.5m (plus probe) ♣ Battery：4x1.5V(AAA) battery（Batteries are not included in the package） ♣ Product Net Weight：142g ♣ Product size：173×59×29mm
