Product Overview

The KR‑302 desktop temperature‑humidity test chamber is compact‑form environmental simulation laboratory equipment. It reproduces diversified climatic conditions including high‑temperature, low‑temperature, constant damp‑heat and alternating hot‑humid cycles within a small footprint. This unit evaluates resistance to heat, cold, dryness and moisture for small‑size electronic assemblies, plastic‑rubber components, automotive accessories, metal hardware and new‑material samples.

Two standard inner‑cavity dimensions are available, and bespoke dimensional adjustments can be supplied for special‑specimen requirements. Suited for labs with limited floor‑space, it supports incoming‑material quality audits, new‑formula R‑D and standard‑compliant product‑certification testing across electronics, automotive, aerospace, chemical and medical‑product sectors.

Core Product Competitive Advantages

1. Compact desktop layout with reliable climate‑control performance Working temperature spans ‑40 ℃ ~ +150 ℃; humidity covers 20 %RH‑98 %RH. Optimised circulating‑air duct design keeps temperature fluctuation ≤±0.5 ℃ and temperature uniformity ≤±2 ℃. Heating speed reaches 1.0‑3.0 ℃/min while cooling speed hits 0.7‑1.0 ℃/min under no‑load conditions, securing stable and repeatable test‑data for small‑batch specimen evaluation.
2. Imported touch‑screen programmable control platform Adopts Korean TEMI colour touch‑screen HMI. PT100 platinum‑resistance sensor delivers precise signal acquisition. Multi‑segment test‑profile editing is supported for unattended cyclic‑climatic‑stress experiments.
3. Full‑import core refrigeration & humidification assemblies Fitted with France Tecumseh fully‑enclosed compressor; choose single‑stage or cascade re‑compression refrigeration. Air‑cooled heat‑dissipation removes requirement for external cooling‑water infrastructure. Stainless‑steel surface‑evaporative humidifier delivers steady‑humidity output and resists limescale build‑up.
4. Robust anti‑corrosion cabinet & human‑centred details Both inner cavity and outer shell adopt SUS304 stainless‑steel sheet. Composite high‑density polyurethane foam plus ultra‑fine glass‑wool cuts thermal‑transfer loss. Multi‑layer insulated viewing window allows direct sample observation without opening the door. Reserved 50 mm / 60 mm cable feed‑through port enables powered‑on specimen testing.
5. Multi‑dimensional comprehensive safety interlock protection Integrated safeguards include leakage‑current protection, compressor overload defence, over‑temperature / over‑humidity cut‑off and water‑shortage alarm. Low‑noise circulating‑fan reduces lab‑background noise level. Mobile‑ready compact structure simplifies relocation and bench‑top placement.

Standard Complete Test Operating Workflow

1. Pre‑Test Preparation Place desktop chamber on flat, stable laboratory bench. Inspect refrigeration unit, humidification water‑supply, circulating‑fan and all safety‑alarm functions. Arrange specimens on adjustable sample shelves; keep adequate clearance for smooth air circulation. Firmly close chamber door and power‑on main‑unit.
2. Program Parameter Configuration Operate touch‑screen HMI: set target temperature‑humidity values, dwell‑time and cycle‑count according to test‑standard. Enable data‑recording function. Let inner‑cavity climate stabilise at set‑points before commencing formal testing.
3. Execute Desktop Temperature‑Humidity Reliability Test Start saved test‑program. Equipment automatically completes heating, cooling, humidification‑dehumidification cycles. Real‑time climatic‑parameters are tracked continuously. Machine auto‑halts after completing preset runtime or cycle quantity.
4. Specimen Retrieval & Result Evaluation Wait until cavity temperature approaches ambient level before opening door. Remove test‑samples. Inspect for deformation, performance drift and appearance degradation. Document observations for QC‑reports. Multiple replicate‑specimen tests are suggested for statistically‑reliable assessment.
5. Post‑Test Tidying Clear sample debris inside cavity. Check humidifier water‑tank liquid‑level. Reset program‑parameters. Shut‑down main power for long‑term idle‑storage. Periodically check door‑seal gasket condition and sensor calibration accuracy.

Safety‑Operation‑Reminder

Do not open chamber‑door under extreme high / low‑temperature running‑condition to avoid scald or frost‑bite hazard. Reliable equipment‑grounding must be completed before power‑on. Avoid frequent short‑interval power‑cycling to protect compressor service‑life. Periodically inspect door‑gasket sealing‑performance and humidifier water‑system cleanliness.
