DO1200 Laboratory Dissolved Oxygen Sensor

The DO1200 Laboratory Dissolved Oxygen Sensor is a compact 12 mm galvanic device designed for portable, laboratory or on‑line measurements. It measures dissolved oxygen from 0 to 20 mg L⁻¹ using an epoxy and Noryl body that tolerates up to 50 °C. The sensor is supplied with a pre‑membraned HDPE cap, while a PTFE cap is offered for high‑UV environments. Standard cable length is 2.5 ft with a tinned lead termination, and longer cables are available for an extra charge.

The HDPE membrane provides a saturation output of 47 mV ± 9 mV, whereas the PTFE option yields 33 mV ± 9 mV, reflecting the common trade‑off between robustness and signal strength in dissolved‑oxygen probes. Typical galvanic sensors in this class achieve an accuracy of ± 0.2 mg L⁻¹ and a response time under 30 seconds under standard laboratory conditions. Pressure rating of 0‑100 psig (7.5 bar) matches the usual specifications for bench‑top equipment exposed to moderate gas pressures. The sensor requires no warm‑up period and uses a single‑point air calibration, a standard practice for quick field verification.

Common users include water‑treatment labs, environmental monitoring agencies and R&D facilities that need reliable on‑site oxygen readings. Week Technology Ltd. offers optional integral ATC elements and temperature‑compensated versions (DO1200TC) to suit more demanding processes. Prospective importers should request confirmation of minimum order quantity, lead time, and preferred Incoterms before placing an order. The supplier’s contact details list a Shenzhen address, but response metrics show no recorded replies, so buyers are advised to verify communication channels early.

Week Technology Ltd. is registered at 16 Floor, Building #3, Zhongke Mansion, Shenzhen, Guangdong 518067, China. The company is listed under the imported tier and carries a harbor trust tier, indicating basic verification by the marketplace. Current response metrics show a zero percent response rate and no recorded response hours, so direct communication should be confirmed before negotiation. The supplier’s profile does not disclose additional corporate history or certifications.

The company’s catalogue includes the DO1200 and DO1200TC dissolved‑oxygen sensors, both employing galvanic sensing technology with optional PTFE membrane caps and integral ATC elements. Sensors are supplied with fast‑responding HDPE caps for laboratory use, and longer cable assemblies can be ordered for on‑line installations. No pricing or MOQ information is provided in the listing, requiring the buyer to request these details directly.
