HERCULES Coolant and Antifreeze Test Strips, 10 Tests: Buyer's Guide for Singapore
Table of Contentsexpand_more
HERCULES Coolant and Antifreeze Test Strips, 10 Tests, are pH test strips that check whether a propylene glycol coolant system is still within its protective range of 0 to 8.5 pH. They are a low-cost, on-site maintenance tool for chillers, gensets, marine engines and process cooling loops in Singapore.
What are HERCULES Coolant and Antifreeze Test Strips?
A coolant and antifreeze test strip is a dip-and-read indicator strip that changes colour to show the pH of a glycol-based coolant, allowing maintenance teams to confirm corrosion protection without laboratory testing. The HERCULES strip covers a 0 to 8.5 pH range and is supplied in packs of 10 tests.
HERCULES is a recognised industrial tool brand, and these strips are stocked by 3G Electric for Singapore buyers who need a simple, repeatable coolant check. They are intended for propylene glycol-based coolants, which are common in food, pharmaceutical and marine cooling systems where low toxicity matters.
How do coolant test strips work?
You dip the strip into a cooled coolant sample, wait for the colour to develop, then compare it against the printed pH scale. The reading tells you whether the coolant is still alkaline enough to protect metal surfaces or has drifted toward acidic conditions where corrosion accelerates.
Because the strip reads pH rather than individual inhibitor levels, it is a screening tool. If the result falls outside the expected range, follow up with a full coolant analysis or a drain-and-refill decision.

Where are these strips used in Singapore?
Singapore's humid tropical climate and dense industrial base make coolant condition monitoring a routine task. Typical users include:
- Marine and offshore operators checking engine and auxiliary cooling systems
- Precision manufacturing plants running process chillers and CNC cooling loops
- F&B and pharmaceutical facilities using propylene glycol for food-safe cooling
- Facilities teams maintaining standby generators and HVAC chiller plants
In all these settings, a drifting pH is an early warning of inhibitor depletion and potential corrosion of heat exchangers, pipework and pump internals.
How to choose the right coolant test strip
- Confirm the coolant chemistry. These HERCULES strips are specified for propylene glycol-based coolants; if your system uses ethylene glycol, verify compatibility before relying on the reading.
- Check the pH range. A 0 to 8.5 pH span covers the acidic-to-neutral region where corrosion risk is highest, which suits routine screening.
- Match pack size to test frequency. A 10-test pack suits small sites or quarterly checks; larger plants may need multiple packs per year.
- Consider the environment. In Singapore's humid conditions, store strips sealed and dry so the indicator pads are not compromised before use.
- Plan the follow-up. Decide in advance what pH threshold triggers a coolant change, top-up or laboratory analysis.
Product comparison
| Product | pH range | Tests per pack | Coolant compatibility | Best for |
|---|---|---|---|---|
| HERCULES Coolant and Antifreeze Test Strips, 10 Tests | 0 to 8.5 pH | 10 tests | Propylene glycol-based coolants | Routine corrosion-protection screening on glycol cooling systems |
As a single-SKU category, the selection decision is straightforward: confirm your coolant is propylene glycol-based and that a 0 to 8.5 pH screening range meets your maintenance regime.

Frequently asked questions
What pH should coolant be? Glycol coolant is normally kept alkaline to inhibit corrosion, so readings near the upper end of the 0 to 8.5 pH strip range are generally healthier than readings drifting toward neutral or acidic values. Always compare against your coolant supplier's specified range.
Can I use these strips with ethylene glycol coolant? The HERCULES strips are specified for propylene glycol-based coolants. If your system uses ethylene glycol, confirm compatibility with 3G Electric before relying on the result, or arrange a full coolant analysis instead.
How many tests do I get per pack? Each pack contains 10 tests, so one pack covers ten individual checks. For multi-chiller plants or fleet maintenance, order several packs to cover a full quarterly or annual schedule.
How fast is delivery in Singapore? These strips are held as Singapore stock, so local delivery is fast for standard orders. Contact 3G Electric for current lead times, bulk quantities and site delivery arrangements.
Do I need calibration or special equipment? No. The strips are a dip-and-read consumable requiring no calibration, power supply or additional instrumentation, which makes them suitable for field checks on marine, offshore and plant cooling systems.
