Why do flexible sensors replace traditional methods for IVD reagent chamber temperature measurement?

In the temperature monitoring of reagent chambers in IVD equipment (such as PCR machines), flexible temperature sensors in IVD reagent chambers are replacing traditional rigid solutions with "contactless bonding and zero risk of accidental contact"

H2: The Two Traditional Challenges of Temperature Measurement in IVD Reagent Storage

H3: Rigid sensors have a large volume (≥ 10 × 8mm) and are prone to knocking over reagent bottles (accident rate of 15%+)
H3: Poor adhesion of curved warehouse walls (traditional sensors can only adhere to flat surfaces, with a temperature deviation of ± 2 ℃)

Our IVD reagent compartment flexible temperature sensor is only 7 × 5 × 0.05mm, which can be attached to the curved compartment wall like a "sticker", and the measured probability of knocking over the reagent bottle is 0.
H3: Accuracy guarantee: ± 0.6 ℃ real-time monitoring (covering the active range of reagents from 4 to 100 ℃)
After being used by a certain IVD manufacturer, the scrap rate of reagents decreased from 8% to 1%, which is precisely the cost advantage of the IVD reagent warehouse flexible temperature sensor.
H3: Easy to install: Tin plated solder pads directly connect to equipment circuits without the need to modify the original structure

H2: Practical Case: Mindray Medical PCR Reagent Warehouse Project

Scenario: Mindray fully automatic PCR instrument (reagent compartment spacing 3mm, curved inner wall)
Solution: Customized 5 × 3mm flexible sensor (attached to the warehouse wall+top)
Effect: Temperature uniformity ± 0.8 ℃ (industry standard ± 1.5 ℃), customer repurchase rate increased by 30%

Misconception 1: Only focusing on price and ignoring accuracy (above ± 1 ℃ will cause reagent failure)
Misconception 2: Neglecting the surface fitting ability (rigid sensors are only applicable to flat surfaces)
Misconception 3: Ignoring Certification (requires ISO 13485 Medical Quality Management System)

Q1: Can the sensor withstand frequent switch vibrations in the reagent compartment?
A: Through 100000 vibration tests (with an amplitude of 0.5mm), there was no detachment/accuracy drift.
Q2: Does it support synchronous monitoring of multiple warehouses?
A: We can provide array sensors (such as 4 pieces for 4 compartments, integrated into 1 acquisition module).
Q3: After sales response time?
A: 24/7 technical support
