z
Indoor specification
z
Where the instrument is not exposed to the direct sunlight
z
Near the water sampling point
z
Where there is a drainage pit for measurement water.
z
Where the atmosphere does not contain dust, mist or corrosive gas.
z
Free from the wind and rain
z
Ambient temperature: 5
°
C to 40
°
C, relative humidity: under 85%.
z
Pollution degree 2
z
No vibration or impact
z
No strong electromagnetical field
z
Altitude: under 2000 m
z
Power supply voltage fluctuation: within ±10% of the rated voltage (90 V to 264 V AC)
Q
Sample water condition
z
Sample water temperature: 5
°
C to 99
°
C
z
Sample water flow rate: 20 mL/min to 200 mL/min
z
Sample water pressure: 0.03 MPa to 0.50 MPa, Pressure fluctuation: within ±0.05 MPa
(within the specified pressure range)
Note
z
Do not block up the discharging tube.
z
Do not raise the discharging tube above the equipment bottom surface.
z
When the discharging tube is blocked up or raised, there is a danger of back pressure building
up, the flow rate changing, and the measurement being influenced.
