Product Details
Brand Name: | CH-S | Place of Origin: | Shaanxi, China | Model Number: | CHNH-812 |
Product Description
Introduction:
The instrument uses Nessler colorimetric measurement of ammonia in the water, the method is simple and high sensitivity. The principle is: ammonia or ammonium ions exist in the free state and sodium's reagent to generates yellow-brown complex, the complex is proportional to the chromaticity and ammonia content.
Feature
High-performance ultra-low power 16-bit microcontroller, standby time of the instrument is up to six months or more.
LCD large-screen LCD, easy and intuitive operation.
Compact equipment, easy to carry.
Saved standard curve 20 and 199 measured values (with a time stamp with the year, month, day, hour, minute, second ammonia values, absorbance and transmittance values. )
Cold light, narrowband interference optical system, good optical stability.
Data power protection.
Host chassis with molded ABS material, IP65 design, good corrosion waterproof and dustproof performance.
Technical Parameter
Measuring range :0.02-25mg / L (range is divided into two: 0 ~ 5mg / L, 5 ~ 25mg / L can be measured over range after dilution.)
Basic error: ± 3% (F.S)
Repeatability: ≤ 3%
Dimensions: 80mm × 230mm × 55mm
Weight: 500g
Normal conditions of use:
Ambient temperature: 5 ~ 40 ℃
Relative humidity: ≤ 85%
Power supply: 4 5 # batteries
no significant vibration and electromagnetic interference, avoid direct sunlight.
