Nitrate Tester

Greentest 1, 2F, 3F, ECO 4F, ECO 6 Nitrate Tester

Keywords: nitrate tester, vegetable nitrate meter, fruit nitrate detector, food safety tester, portable nitrate tester

Chemical-free nitrate screening in about three seconds, with a 30–9999 mg/kg range and an 85 g pocket body.

The Greentest 1 is a pocket-sized nitrate tester for vegetables and fruits. It is the 2-in-1 model of the Greentest nitrate tester series and works without any chemical reagent: the probe applies a precisely regulated electrical current to the specimen, and the built-in algorithm converts the measured electrical conductivity into a nitrate reading in mg/kg. Results appear on a 320×240 TFT color display in about three seconds.

The series covers five order numbers so that one platform can be matched to different testing needs: Greentest 1 tests vegetables and fruits (2 in 1), Greentest 2F adds meat and fish (4 in 1), Greentest 3F adds water TDS as well (5 in 1), and Greentest ECO 4F / ECO 6 add background radiation and timer functions (6 in 1). All models share the same 85 g body, USB charging and up to six hours of operation.

Key Features

1.  2-in-1 Testing — measures nitrate in vegetables and fruits with a single device, so produce checks no longer need separate instruments.

2.  Three-Second Reading — a complete measurement takes about 3 seconds, which keeps screening fast enough for routine use.

3.  Wide Detection Range — covers 30–9999 mg/kg of harmful substance concentration, from lightly contaminated to heavily contaminated samples.

4.  Chemical-Free Method — the probe applies a precisely regulated electrical current to the specimen; no reagent, strip or sample preparation is required.

5.  Proprietary Algorithm — nitrate content is calculated by comparing the specimen's electrical conductivity against a database obtained from mass spectrometer testing of similar specimens under laboratory conditions.

6.  Pocket Portability — 122×52×14 mm and only 85 g, so the tester fits in a pocket and can be carried to markets, farms or kitchens.

7.  Long Runtime and USB Charging — Li-Ion battery provides up to 6 hours of use, and the tester can also run from USB at 5 V / 250 mA.

8.  TFT Color Display — 320×240 color screen with an intuitive interface for quick reading of results.

9.  Expandable Series — the 2F, 3F, ECO 4F and ECO 6 models extend the same platform to meat, fish, water TDS, background radiation and timer functions.

How to Use

1.  Prepare the Specimen — take a clean vegetable or fruit sample to be tested.

2.  Apply the Probe — bring the probe into contact with the specimen; it applies a precisely regulated electrical current.

3.  Wait About 3 Seconds — the proprietary algorithm compares the conductivity of the specimen against its laboratory database.

4.  Read the Result — the nitrate concentration is displayed in mg/kg on the TFT color screen, ready to be compared with reference values.
