Import Acidity Test Kit — Buy in Bulk from Supplier in India

The acidity test kit from Leishangthem International, based in New Delhi, India, provides a portable analytical solution for measuring total acid number (TAN) in transformer insulating oils. The kit is designed for field use by maintenance engineers who need rapid, on-site assessment of oil degradation without sending samples to external laboratories. It targets the petroleum-based mineral oils commonly used in power transformers, where oxidation products increase acidity and accelerate insulation breakdown. The supplier notes the kit includes comprehensive testing components with easy-to-follow instructions, though exact reagent volumes and detection ranges are not specified in the listing.

Transformer oil acidity is typically expressed in milligrams of potassium hydroxide per gram of oil (mg KOH/g), with fresh oil showing values below 0.03 mg KOH/g and condemned oil exceeding 0.40 mg KOH/g per IEC 62021 and ASTM D664 standards. The test chemistry involves titrating oil dissolved in a solvent mixture against alcoholic KOH using a colorimetric indicator, usually phenolphthalein or a mixed indicator for sharper endpoints. Leishangthem International's kit appears to follow this standard methodology, though buyers should confirm whether the included reagents are pre-standardised and whether the kit covers the full 0.01 to 2.00 mg KOH/g working range typical for portable TAN kits. The compact design suggests it is intended for routine preventive maintenance rather than laboratory-grade precision work.

Primary buyers include utility maintenance departments, industrial plant engineers, and transformer service contractors across South Asia and export markets. The kit supports condition-based maintenance programmes that extend transformer life and reduce unplanned outages. For trade terms, the listing mentions flexible minimum order quantities and FOB or CIF shipping options, though exact MOQ thresholds, unit pricing, and lead times are not stated. The supplier claims ISO certification, but the specific standard and certifying body are not identified. Buyers should request the certificate number and scope before placing orders, and confirm whether the kit requires any import licences or hazardous material documentation for the alcoholic reagent components.

Leishangthem International operates from 42, Shakarpur Khas, Shakarpur, New Delhi 110092, Delhi, India. The company holds a harbor trust tier on the marketplace, which represents a baseline verification level rather than an advanced accreditation. The response rate is recorded at 0.00 percent with zero average response hours, indicating no historical buyer engagement data is available through the platform. This absence of response metrics should factor into buyer due diligence, as it means the supplier's communication reliability and quotation turnaround are unverified.

The supplier profile provides no information about establishment year, employee count, manufacturing facilities, revenue, or specific client references. The description frames Leishangthem International as serving engineers and maintenance professionals in power generation and electrical industries, but no named projects, utilities, or export destinations are listed. Buyers should independently verify the company's registration with the Ministry of Corporate Affairs or relevant Indian trade bodies, and request references from past transformer oil testing equipment purchasers before committing to substantial orders.
