Shelf life of a packaged food depends on both what is inside and what keeps air and moisture out. Our packaged food testing instruments let a QC lab check both sides with one set of equipment. As packaged food testing instruments manufacturers in India and suppliers in India, we supply food factories, co-packers and testing labs.
Product-side instruments include the halogen moisture analyzer, water activity meter, Brix refractometer and texture analyzer, which help control recipe, crispness and microbial risk. Package-side instruments include the oxygen and water vapour transmission testers for films, seal strength and puncture testers for pouches and lids, and compression testers for cartons, jars and cans. A portable headspace analyzer checks oxygen and carbon dioxide in modified atmosphere packs.
Food plants normally split the group, with moisture, water activity and seal strength at the line and OTR, WVTR and texture work in the central lab.

Digital refractometer that reads soluble solids in Brix for sauces, juices, syrups and jams from a single drop. Used for formulation control and finished pack checks in food packing plants.
Compression tester that crushes cartons, cans or jars between flat platens to find top-load strength. Used by food makers to size corrugated shippers and verify pallet stacking height.
Portable gas analyzer that samples the headspace of sealed food packs to measure oxygen and carbon dioxide. Used by MAP meat, bakery, snack and produce packers.
Halogen lamp moisture balance for rapid moisture determination in flour, spices, snacks and powders. Used by food plants for incoming raw material checks and finished pack release.
Coulometric OTR tester that measures oxygen permeability of films and laminates in cc per square metre per day. Used by snack, dairy and meat packers to qualify barrier packaging structures.
Tester that measures force required to puncture film or laminate with a probe. Used to select packaging for sharp edged contents like bones and dry pasta.
Tensile-type tester that measures heat seal strength of flexible food pouches and laminates. Used by snack, spice and ready meal packers to confirm pack integrity.
Texture analyzer that runs compression, penetration, shear and tension tests on packaged foods with interchangeable probes. Used by food manufacturers to measure firmness, chewiness and crispness of bakery, snack and dairy products.
Benchtop water activity meter for dry and semi-moist foods that reads relative humidity above a sealed sample. Used by food packers for shelf life, microbial stability and moisture migration checks.
Cup-type or sensor instrument for water vapour transmission rate of films, used by biscuit, cereal and snack packers to decide pack barrier needs. Runs at controlled temperature and humidity chamber conditions.
| Function | Products | What to confirm |
|---|---|---|
| Product composition and quality | Moisture Analyzer Halogen for Food Products, Water Activity Meter for Packaged Foods, Digital Brix Refractometer for Packaged Food Liquids, Texture Analyzer for Packaged Food Products | Measurement range, sample size, temperature control, probe or fixture options and whether results need printing for batch records. |
| Barrier performance of packs | Oxygen Transmission Rate Tester for Food Packaging Films, Water Vapour Transmission Rate Tester for Food Packaging | Test cell area, humidity and temperature range, film thickness limits and standard method such as ASTM D3985 or ASTM F1249. |
| Seal and film strength | Seal Strength Tester for Food Pouch Packages, Puncture Resistance Tester for Food Packaging Films | Seal width and jaw size, load cell range, test speed and puncture probe geometry. |
| Pack atmosphere and stacking | Headspace Oxygen and CO2 Analyzer for Modified Atmosphere Packs, Food Package Compression and Stacking Tester | Gas sensor ranges, sampling needle type, platen size and maximum compression load. |
Packaged food instruments mix product tests, such as water activity, Brix, texture and moisture, with package checks like headspace gas and barrier. Flexible packaging instruments concentrate on the pouch and film alone, so they go deeper into lamination, hot tack, friction and tear. A food converter uses the pouch range, while a food manufacturer needs this range for the full product and pack story.

The complete Packaged Food Testing Instruments range (10 products), in alphabetical order:
Look at the number of test cells, measurable transmission range, and temperature and humidity control, since results vary strongly with conditions. Confirm the method, ASTM D3985 or ISO 15105-2 for oxygen and ASTM F1249 or ISO 15106 for water vapour, plus the film thickness and sample size. High barrier films need sensitive sensors.
Pick the range suited to your foods, usually 0.1 to 1.0 aw, with accuracy near 0.01 aw and temperature control of the sample chamber. Check sample cup size, calibration salts or standards supplied and recovery time between samples. Dry snacks, spices and bakery goods all benefit from stable chamber temperature.
Check which gases are measured, oxygen and CO2 as a minimum, the measurable range, sampling needle size and whether septa are supplied. Portable units suit line checks on modified atmosphere trays, while a result printout or data logging helps for audits. Confirm battery life and calibration gases.
Packaged snack, bakery, dairy, beverage, spice and ready meal producers, co-packers, food packaging converters, export houses and food testing laboratories. A food plant typically orders a moisture analyzer, water activity meter and seal tester first, then adds OTR and WVTR testers when it develops longer shelf life products or new films.
Moisture content is the total water present, while water activity shows how much is free and available to microbes. Two foods with equal moisture can have different aw, so shelf life and safety decisions rely on aw.
It compresses, penetrates, shears or pulls a sample at set speed and records force against distance. Hardness, crispness, chewiness and adhesiveness are derived from the curve, which helps in recipe development and quality control.
A strip is cut across the seal, the two ends are clamped in a tensile-type tester, and the force required to separate them is recorded. ASTM F88 is a common method. Low values point to poor sealing temperature or contaminated seals.
Yes. We make the instruments in India and supply plants, labs and distributors across the country and overseas. Tender specifications and datasheets are available, and installation and training can be arranged.
Brix gives the soluble solids in juices, jams, sauces and syrups. A digital refractometer reads it in seconds, so product consistency and ingredient dosing can be checked before filling.
As established manufacturers and suppliers for tender requirements from India, we undertake civil laboratory and industrial testing tenders as well as bulk and OEM supply of mechanical engineering and testing laboratory equipment. Please forward your tender specifications and our team will prepare a detailed quotation for Packaged Food Testing Instruments.
Send us your equipment list or tender specification. We quote against IS, BS, EN, ASTM and AASHTO standards and ship to 90+ countries.
