TS-620 Turbidimeter Online Turbidity Meter
The Apure TS-620 is an online turbidity meter for use with a matched optical sensor in water and wastewater monitoring. Select the sensor option and working interval, then confirm the measurement method, reporting unit and required outputs.
- Easy to operate
- Widely used
- Automation
The TS-620 monitors turbidity with its matched optical sensor. Turbidity is an optical measurement influenced by particle properties and the measuring arrangement; it is not a direct measurement of suspended-solids mass or drinking-water safety.
Install and check the optical measurement
- Place the sensor in representative water within the approved temperature and pressure limits. Avoid trapped bubbles, deposits, direct aeration plumes and unapproved reflections from nearby walls or the vessel bottom.
- Clean the optical window using the supplied procedure, check for scratches and fouling, and verify with the specified standards or reference samples after service.
- Record the sensor/controller identities, measurement method, unit, calibration reference, temperature and installation. A change in colour, particle properties or sampling location can change the optical response.
The TD-400 and TD-5000 entries below are separately listed options. Confirm the selected sensor and interval; do not combine them into one universal range. The existing relay descriptions differ between entries, so obtain the actual terminal drawing and relay/output list for the ordered controller.
CHARACTERISTICS:
Operation and integration
- Maintain the specified sample and installation conditions; changes in flow, pressure, bubbles or particle distribution can affect an optical reading.
- Confirm the supplied display values and unit. A percentage or current-output display is not an independent measurement of suspended-solids mass.
- For the listed 4-20mA, relay and RS485 options, use the actual terminal drawing and communication specification. Confirm enabled functions before control-system integration.
- Follow the documented two-point calibration procedure using the specified references. Keep a separate verification result and maintenance record.
| Electrode measurement range | Resolution | Precision |

Confirm the ordered sensor/controller pair and the actual relay/output schedule. The existing entries use different relay descriptions; the table has been retained as listed rather than choosing an unverified count.
