Ishida bench and retail scales are sold in the United States through Rice Lake Weighing Systems, which is why you will see them listed as Rice Lake Ishida. MNM Scales has sold, calibrated and repaired scales for over 30 years from our shop in Cypress, Texas. This page covers the Ishida scales we sell, the Ishida models we service, repair, calibration, manuals and legal-for-trade use in Texas.

Ishida IGX for carcass or hanging weighing

The Ishida IGX is a bench (platform) scale. For carcasses and other hanging loads, a hanging scale on the rail or hook does the job: see our hanging and crane scales, or call us and we will match a scale to your rail, capacity and division.

Ishida scale repair

Our scale repair service in Houston covers Rice Lake Ishida bench scales such as the iPC and IGX. We repair Ishida scales in our Cypress shop or on-site across Greater Houston; the on-site service call is $295 + $2 per mile, and repairs are quoted per job. Outside Houston, ask about mail-in service.

Symptom	Likely cause	What we do
iPC or IGB will not turn on or shuts off	Weak D batteries, auto power-off setting, AC adapter or jack	Test the power path and the adapter (Rice Lake 75473 fits the iPC, iPC-WP, IGX and IGB)
IGX display stays blank	120 VAC supply, power cord, display or main board	Check the supply and boards and replace failed parts
Will not zero or drifts	Load cell strain from a dropped load, moisture, debris under the platter	Inspect and test the load cell; see our won’t zero and drifting guide
Error or overload code	Load over capacity, load cell signal out of range	Diagnose the code; see our scale error codes guide
Reads wrong with a known weight	Calibration out, overload stop or load cell damage	Repair as needed, then recalibrate with test weights
Keys do not respond	Keypad membrane or cable	Replace the keypad or cable

Ishida scale calibration

We calibrate Ishida scales with NIST-tested weights in our Cypress shop, by mail-in, or on-site with our own test weights. Pick the tier by the scale’s capacity:

• iPC (15/30 lb or 30/60 lb) and Nova-II: in-house calibration with a certificate $250 or NIST calibration with a NIST-traceable certificate $595 (6.2 to 35 kg tier).
• IGX and IGB (150 lb or 300 lb): see in-house calibration for 35 to 150 kg scales and NIST calibration for 35 to 150 kg scales for current pricing.
• On-site in Greater Houston: $295 + $2 per mile per visit; see on-site scale calibration in Houston and industrial scale calibration.

Ishida scale manuals

Need the operating or setup manual for an Ishida scale? Call (832) 290-3120 or send a request with the model and Rice Lake part number from the data plate, and we will help you get the right manual for that model. If the scale needs legal-for-trade setup or calibration work, we can quote that at the same time.

Using Ishida scales for legal-for-trade weighing in Texas

For selling by weight, we recommend an NTEP Ishida scale: the IGX or IGB (NTEP CC 05-020, Class III), the iPC or iPC-WP (NTEP CC 02-139, Class III), or the Nova-II (NTEP CC 98-001A1, Class III), or one of our NTEP legal-for-trade scales. TDA does not require an NTEP certificate for every device, but the scale must meet NIST Handbook 44 and suit its use; some scales do need one, so we recommend NTEP models and can check yours. TDA explains this in Legal for Trade Scales in the State of Texas (PDF). See our NTEP guide, TDA scale certification guide and legal-for-trade scale calibration in Texas.
