The price range of temperature monitoring instruments for hot runner calibration varies greatly depending on the number of channels, accuracy, and functions. Specifically:
1. Basic Model (for routine calibration in production environments)
Parameters: 2-channel synchronous acquisition, accuracy 0.1℃, supports K/J graduations, handheld and portable, no data storage.
Price Range: Domestic, 800~1500 RMB. Fully meets the needs of most hot runner on-site calibrations, offering the best cost-performance ratio.
2. Mid-Range Model (with data storage + multi-channel)
Parameters: 2~4-channel synchronous acquisition, accuracy 0.1℃, supports multiple graduation numbers, with data storage and export.
Price Range: Domestic, 1500~3000 RMB. Suitable for scenarios requiring calibration record storage and quality traceability.
3. High-End, High-Precision Model (for precision batch calibration)
Parameters: 4~8-channel synchronous acquisition, accuracy ≤0.05℃, supports all graduation numbers, with professional analysis software.
Price Range: Domestic 3000~8000 RMB; Imported brands (such as Yokogawa and Fluke) 8000~20000 RMB, only for laboratory batch calibration or high-precision metrological traceability.
Supplementary Note: Domestic equipment now fully meets the accuracy requirements of hot runner calibration. For the same parameters, imported equipment is 2~3 times more expensive than domestic equipment. For ordinary production calibration, basic/mid-range domestic models are sufficient, as they are low-cost and adequate.
